The “Server With Specified Hostname Could Not Be Found” error means your device cannot turn the server name into an IP address because of DNS or network problems.
When you see the line server with specified hostname could not be found, it feels vague and technical, yet it always points to one simple thing: your device tried to reach a server by its name and failed. That failure sits either in your network path, your DNS settings, your app settings, or on the server side itself.
This guide walks through what the message really means, why it shows up in places like Apple Music, the App Store, browsers, and developer tools, and how you can clear it on your own. You will move from quick checks that take seconds to deeper fixes that touch DNS, VPN profiles, and app settings.
Quick check: Work through the early steps in order. They safely rule out the basics, so you only touch advanced settings when that effort is actually needed.
What The “Server With Specified Hostname Could Not Be Found” Error Means
Every time you type a web address or an app reaches out to a service, your device sends a request to a human-readable name such as api.example.com. DNS (Domain Name System) turns that name into an IP address so the request knows where to go. If DNS fails, you end up with a message that a server with specified hostname could not be found.
Your device is not saying the server number does not exist at all. It is saying, “I cannot look up the address for this label.” That can happen because the name is wrong, your DNS servers are down, the request is blocked by a VPN or filter, or the server owner changed settings and your device still uses old data.
On Apple devices and Macs, this wording shows up often when Apple Music, the App Store, or a game client cannot reach an Apple server. On other systems, the message might appear in browsers, streaming apps, or developer tools when a hostname check fails during a network call.
Once you understand that this is a lookup problem, the fixes make more sense: you either help the device reach DNS, give it better DNS servers, correct the hostname, or clear the blockers sitting between your device and the internet.
Where You Usually See A Server Hostname Error
The wording stays almost the same, yet the context changes the likely cause. Knowing where the message shows up helps you pick the right track right away.
- Apple Music Or TV Apps — The client cannot reach Apple’s media servers, often due to DNS, VPN profiles, or router filters.
- Mac App Store Or iOS App Store — App downloads or updates stall because the store domain cannot be resolved on your network.
- Browsers And Web Apps — A website’s hostname fails to resolve, pointing to DNS outages, typos in the address, or ISP filtering.
- Developer Projects — A test call from a Mac, iOS app, or local tool cannot reach a backend hostname due to sandbox rules or bad configuration.
- Home Servers And Media Boxes — A client such as a media app cannot find a local hostname inside your home network, often due to router DNS quirks.
Each of these situations shares the same base pattern: the software expects DNS to answer, DNS fails, and the client shows the message. The path you follow next depends on whether other apps on the same device work, whether only one service breaks, and whether other devices on the network share the problem.
Quick Checks Before You Chase Complex Fixes
Quick check: Run through these small steps before you touch DNS records, router menus, or developer settings. They rule out simple network flukes that trigger the same error text.
- Test Other Websites Or Apps — Open a few well-known sites or apps that use different services and see if they load as usual.
- Toggle Wi-Fi Or Airplane Mode — Turn Wi-Fi or mobile data off for ten seconds, then turn it back on and retry the same action.
- Restart The Device — Power down your phone, tablet, or computer completely, wait a few seconds, then turn it back on.
- Try Another Network — Connect to a different Wi-Fi network or use mobile data instead and check if the hostname error still appears.
- Confirm The Hostname — Check the exact spelling of the server name, including dots, dashes, and subdomains.
If everything fails on one device but works on another device on the same Wi-Fi, your next steps sit on that single device. If nothing on the network can reach the target service, look at the router, DNS, or ISP side.
Common Causes And First Fixes
| Symptom | Likely Cause | First Fix |
|---|---|---|
| Only one app shows the hostname error | App cache, sign-in, or app-specific settings | Force quit the app, sign out and back in, then retry |
| Only one device shows the error | Local DNS cache or device network profile | Restart the device and reset network settings if needed |
| All devices fail to reach the same service | Router DNS issues or ISP filtering | Reboot the router and change DNS to a public resolver |
| Error appears only when VPN is active | VPN DNS servers or blocked domains | Disable the VPN profile or swap to another VPN endpoint |
Fixing The “Server With Specified Hostname Could Not Be Found” Error
Once you have ruled out short dropouts and typos, it is time to work through network and DNS settings. The goal is to ensure your device can ask a healthy DNS resolver for the hostname and send traffic out without filters blocking the request.
Step 1: Check DNS Settings On Your Device
- Use Automatic DNS First — On phones and tablets, open Wi-Fi settings, tap the current network, and set DNS back to automatic if it was set manually.
- Try A Public DNS Resolver — If automatic DNS fails, switch to well-known resolvers such as
8.8.8.8and1.1.1.1in your network settings. - Disable Custom DNS Apps — Turn off any DNS-changing apps or profiles and check whether that clears the hostname error.
Deeper fix: On a Mac or Windows computer, test DNS from a terminal or command window by pinging a hostname and then pinging the same server by IP address. If the IP works but the hostname fails, you have a DNS lookup problem, not a raw connectivity problem.
Step 2: Clear Local Network Caches
- Restart Router And Modem — Pull the power cable, wait thirty seconds, plug it back in, and let the network come up fully.
- Flush DNS Cache On Computers — On macOS, run
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponderin Terminal, then retry the request. - Reset Network Settings On Phones — Use the system option to reset Wi-Fi, mobile, and VPN settings if recurring hostname errors appear only on that device.
Step 3: Turn Off VPN, Proxy, And Security Filters
- Remove VPN Profiles — Instead of just switching a VPN off, delete its profile in system settings, then test the failing app again without any VPN in place.
- Disable Custom Proxy Settings — In Wi-Fi advanced settings, set proxy to off or automatic so traffic does not route through a misconfigured proxy.
- Pause DNS Filters — If you use parental controls or DNS block lists, pause them briefly to see whether they block the hostname in question.
Many Apple Music and App Store cases clear as soon as old VPN or proxy profiles are removed, because those profiles leave stale DNS paths that do not match your current network anymore.
Advanced Fixes On Apple Devices And Computers
On Apple platforms this message is often tied to specific apps such as Apple Music, TV, and the App Store. When basic steps do not help, a few extra device steps are worth trying before you assume a bigger outage.
Apple Music And App Store On iPhone Or iPad
- Check Apple System Status — Visit Apple’s status page in a browser and confirm that Apple Music, TV, and the App Store show green indicators.
- Force Quit And Reopen The App — Swipe the app away from the app switcher, wait a moment, then open it again and retry the same action.
- Check Date And Time Settings — Set date and time to automatic so that secure connections to Apple servers do not fail due to a skewed clock.
- Sign Out And Back In With Apple ID — Sign out of the service inside the app, restart the device, then sign in again and test downloads or streaming.
- Reset Network Settings — If nothing else works, reset network settings, restart the device, and connect to Wi-Fi again to remove hidden network glitches.
Mac App Store And Network Calls On macOS
- Sign Out Of The Mac App Store — Use the Store menu to sign out, quit the App Store, then reopen it and sign back in.
- Enable Debug Menu For The Store — Some users clear stubborn cache problems by enabling the debug menu, then clearing cookies and store cache before retrying downloads.
- Check Sandbox Outgoing Connections — For developer projects in Xcode, enable outgoing connections in the app’s capabilities so network calls to hostnames are allowed.
- Test With A Different macOS User — Create a new user account, sign in, and test the same store or app action to see whether the error follows your profile or the whole system.
When the same hostname request works on another macOS user account, the problem usually lives in per-user cache files or settings. Clearing those via the debug menu or by resetting network-related preferences often helps.
When The Server Side Causes The Hostname Error
Sometimes you can confirm that your devices, router, and DNS settings all behave as they should, yet the server with specified hostname could not be found message still appears for the same app or domain. In that case, the hostname itself might be broken or misconfigured by whoever runs the service.
Common server-side causes include expired DNS records, wrong DNS entries for new domains, misconfigured load balancers, or regional blocking at the DNS level. When any of these exist, every device using standard DNS resolvers will fail to reach the same hostname, no matter how many times you restart your router.
- Check The Hostname On A DNS Tool — Use a public DNS lookup site to see whether the domain returns an IP address or fails from several regions.
- Compare Different DNS Resolvers — Test the hostname through your ISP DNS, then again through a public resolver to see if only one path fails.
- Ask The Service Owner For Status — If a company provides the app or API, reach out through its status page or contact channel and share a screenshot of the error.
If public DNS checks show no records for the hostname, there is nothing you can change locally to fix that. The owner of the domain has to correct DNS entries so that clients across the internet can find the server again.
Habits That Help You Avoid Hostname Problems
You cannot prevent every DNS outage or misconfigured app update, yet a few habits reduce how often you see this line across your devices. They also make diagnosis faster next time a hostname problem appears.
- Keep Network Gear Updated — Install firmware updates for routers and mesh systems so DNS and security features stay stable.
- Use Reliable DNS Providers — Pick DNS servers from respected providers or your ISP, and avoid stacking many DNS-changing apps on the same device.
- Avoid Layered VPN Chains — Running several VPNs or proxy tools at once multiplies the chances that one of them blocks your hostname queries.
- Document Custom Hostnames — If you run home lab servers or local services, keep a small list of hostnames and IPs so you can spot typos quickly.
- Check Status Pages Early — When a single app fails with hostname errors, glance at the vendor’s status page before spending time on deep tweaks.
The next time you see “Server With Specified Hostname Could Not Be Found,” you now know that the message points straight at hostname lookup and network path, not at some vague mystery. Start with basic connectivity checks, step through DNS and VPN settings, match your device behavior with other devices, and you will either clear the issue yourself or gather clear evidence to share with the service owner.
