Crash when version check

[dalbodeule]

Describe the bug While querying the BungeePerms Jenkins server's API for version checking during plug-in version checking, it is presumed to be an error when the server is not properly connected.

To Reproduce Steps to reproduce the behavior:

1. Implement an environment where other Internet environments are in place and unable to connect to BungeePerms Jenkins server.
2. In this state, run the server that contains the BungeePerms plug-in.
3. Wait for the server to power up completely and the server will crash.
4. If you take the source of the V4 branch and force version checking to be disabled, the server will work.

Expected behavior This error is presumed to be due to lack of action in case the version check is not done properly.

[04:20:17] [Spigot Watchdog Thread/ERROR]: If you see a plugin in the Server thread dump below, then please report it to that author
[04:20:17] [Spigot Watchdog Thread/ERROR]:       *Especially* if it looks like HTTP or MySQL operations are occurring
[04:20:17] [Spigot Watchdog Thread/ERROR]: If you see a world save or edit, then it means you did far more than your server can handle at once
[04:20:17] [Spigot Watchdog Thread/ERROR]:       If this is the case, consider increasing timeout-time in spigot.yml but note that this will replace the crash with LARGE lag spikes
