Executes Get_Update_String on startup to check for newer versions by querying the GitHub API. Because the DNS was unreachable, urllib.request.urlopen(URL) hung indefinitely waiting for a response, ultimately throwing a socket.gaierror: [Errno -3] Temporary failure in name resolution. FIX: Add a timeout so restarting the container when the internet is down allows you to continue. Signed-off-by: weedy <weedy2887@gmail.com>

Add timeouts so threads don't dead lock.
After this got fixed I figured out I need to adjust uWSGI config with env vars.
uWSGI was configured to spin up 4 workers concurrently in lazy-apps mode.
When DNS failed and delayed the startup, all 4 workers attempted to initialize the local SQLite database simultaneously. SQLite does not support highly concurrent writes, resulting in sqlite3.OperationalError: database is locked, which then caused the APScheduler to throw a RuntimeError and also crashes the entire container.
I don't know how deep you want to go with this.
But my internet is currently down and I got stuck dealing with broken homelab stuff all over the place.
