Some users seem to be experiencing timeout issues even with this mod installed. (See #94)
If you have this problem, can you make sure that your KeepAlive packet interval is set to 15 seconds? Keep in mind that the read timeout is specified in seconds, but the login timeout is specified in ticks.
If you can also ensure that a message like this: on 1.14+
occurs in the console, that would be great. The message doesn't seem to appear in the log because of some weird Forge stuff.
A reminder that the timeout options are server-sided (except for the read timeout which has some client-sided functionality). The configuration options will be less confusing in the 1.16.4 rewrite.
EDIT: In the rewrite, the configuration options are better-organised and documented.
