Hi @Griffinbloob, welcome to the forums, did you not have any issues before when connecting to servers?
Does it happen with both unofficial and official ones?
We also recommend that you try to follow the suggested steps below:
Check out what is your current NAT type:

If you’re able to access your router’s settings, make sure that UPnP is enabled.
If possible, confirm that all required ports are being forwarded:
