Solved: “A Server With This Hostname Cannot Be Found” In iOS

For the past few days whenever I’ve been using my iPhone on a cellular connection I’ve been unable to play podcasts or stream music, or do anything else that requires an Internet connection. The title of this post refers to the error I was receiving in Apple Music whenever I tried to play something.

After spending a bit of time diagnosing the issue it became apparent that the problem originated in the VPN service that I use to scan for, and block, trackers and malicious content. Specifically, the 1Blocker application currently has a problem when it uses DNS Proxy-based scanning for its firewall.

While one solution involves disabling 1Blocker’s VPN functionality entirely1 you can also switch to HTTP Proxy-based scanning in 1Blocker to resolve the issue. To do so:

  1. Open the 1Blocker application
  2. Open the Firewall tab
  3. Click the ‘…’ in the upper right corner
  4. Select ‘HTTP Proxy’

At the moment the company is asserting that the problem originates from “an ongoing connectivity issue that affects some mobile network operators.” No further information has been provided.

It’s possible that this will be resolved if carriers fix whatever is wrong on their end, though there isn’t a public ETA for this occurring at the moment.


  1. Settings > VPN > the (i) button beside 1Blocker > Turn off ‘Connect on Demand’ > return to VPN and set status to ‘Disconnected’ ↩︎
