Dev build doesn't work with my 1.20.2 Minehut proxy server. If there is any fix with this in the future, Please LMK!

If people would check the jenkins they would realize that build 669 is 1.20.2.
For some reason there is an eighty character limit on reviews, so this is just filler text that has zero meaning what so ever to the review.

Please update the plugin to support 1.20.2 version. This would be amazing if it will be updated to the latest.

Latest build doesn't work on 1.20.2 and developer doesn't update it for 1.20.2 too.

Use latest dev build...
here it works on 1.20.2 (if not: post the error.)

PS: version 5.1.0 is not a dev build version number...

Can confirm, using 5.0.0 dev build fixes the issue. https://ci.dmulloy2.net/job/ProtocolLib/
