Original GitHub issue: https://github.com/binwiederhier/ntfy/issues/1200

🐞 Describe the bug
Adding a topic subscription on my Iphone when connected to my wifi the app responds with "The internet connection appears to be offline".

💻 Components impacted

💡 Screenshots and/or logs

🔮 Additional context

Ntfy.sh is self-hosted in docker, behind Nginx Proxy Manager, and I am using Tailscale for remote access. If I disconnect from my Wifi the subscription works.

The DNS server is the same both on and off wifi since I access via Tailscale.

If I try the same operation on my mac I initially get the same result, but then it asks if I want the app to be able to access local network resources. If I respond "yes", the subscription is successful. But, there are still no notifications coming through. I have verified that Ntfy on my Iphone can access local network resources, but on this device it continues to give an error.

Pretty sure I've got the same issue, Ntfy in docker, proxied with Traefik internally to https://ntfy.internal.my.domain. My router is a on my Tailnet and advertises my LAN to other devices via the Tailscale subnet router feature. If I am connected to my LAN directly I cannot access my Ntfy server via app, although I can get to it in Safari without issues. The problem persists with or without the Tailscale VPN connection...as long as my phone is on the LAN the app will not connect. If I am on any other network than my LAN with Tailscale turned on I can connect to Ntfy via the app just like I would expect.

I had the same issue and had to enable "Local Network" for the ntfy app in iOS Apps settings for notifications to work.

Ideally the app would prompt for this permission after first opening.
