Question Server network suddenly stopped working (won't let players join)

[Domnom09]

Hi everyone, so I just have a question about Waterfall networks. I have a server network that uses Waterfall as the proxy server software. I am aware of the current Waterfall situation and that it is no longer maintained but I figured it will not be a problem for the next few months. I recently went on a vacation and before I left, everything was working perfectly. After I came back, I wanted to continue with it and I noticed it won't let me join. I thought you guys could maybe help me further with this problem. I noticed that it matters what backend server I try connecting to. The ones that use PaperMC 1.20 or below let me join without a problem. 1.21 servers will refuse to let players join. The client says Encrypting... but when I look at console, the same second I connect to the backend server, I get disconnected from it. Console for the backend server doesn't say anything though. The Encrypting... text stays on my screen for around 15 seconds. Then it says 'ReadTimeoutException : null'. I thought maybe someone could help me further with this problem.

Sorry, but what did you expect? The waterfall discontinuation was announced before 1.21 was even released, iirc. They seem to be still syncing waterfall with somewhat recent upstream commits, but the project is dead.

but I figured it will not be a problem for the next few months.

Why delay switching? You know you need to anyway, and you even realized it yourself by saying that you thought it would maybe work for the next few months. Just use velocity or switch to Bungee(if you really need to use the platform)

You will have to do that anyway, so why not just do it now?
