If you launch the app with wifi off, the app is disconnected, as it should. If you then connect, Godot can't reconnect to the given hostname.

The error seem to indicate that Godot tries to resolve the hostname once, then caches that and doesn't try again.

This is a function that tries to reconnect every 3 seconds in case of failure. I was disconnected for the first 2 ~ 3 lines, but I was connected after that

To Reproduce
Steps to reproduce the bug:

1. Either set ConnectionChecker's print_debug_strings to true (or observe the connection light in any Practice)
2. disable your OS connection
3. launch the app
4. Note that the connection light in Practices says you're offline, and ConnectionChecker prints "attempting to connect..." repeatedly
5. Note that the Errors tab contains connect_to_host: Condition "ip_candidates.empty()"
6. Turn your connection OS on
7. Despite WebSocketClient.connect_to_url being called again, and the server being available, Godot won't connect

Expected behavior

Godot should try to resolve the hostname again (if the error is correct and if this is the problem)
