Bug Description

Using the fabric1.20.1 client that only installs viafabricplus-2.8.7 and fabric-api-0.84.0+1.20.1, it is not possible to join the 1.20.2 server that only installs fabric-api-0.90.0+1.20.2, Viafabric-0.4.11+50-dev, and ViaVersion 4.9.3-SNAPSHOT. The image below is evidence and error messages for joining the server
Note: The network compression threshold of server.properties has been changed to a larger number, and the max pps and tracking period in the configuration file of viversion.yml have been changed to -1

Steps to Reproduce

1. Start the 1.20.2 fabric server
2. Start the 1.20.1 fabric client
3. Client joining server
4. Unable to access server
   Note: Testing has been conducted on different computers on the same network as the client and server, as well as on the same computer environment. Testing has also been conducted on different networks, but access to the server is not possible

Expected Behavior

Checklist

• I have checked if this is specific to ViaFabric platform, and doesn't happen when running it on other platforms (Paper/Sponge/Velocity/Waterfall).
• I have included a ViaVersion dump.
• If applicable, I have included a paste (not a screenshot) of the error.
• I have tried the latest build(s) from https://ci.viaversion.com/ and the issue still persists.

1.20.2 is no longer supported, Please update to 1.20.3/1.20.4.

Many mods on my server and client have not been updated to 1.20.3/1.20.4, so the only solution now is to wait for these mods to be updated?

Yes since 1.20.2 is quite buggy in terms of client support - You could attempt to update fabric API but i cannot be sure if this would resolve your problem that way. (+ 1.19 and older clients have yet to be fixed due to either chat reporting system or something else breaking them)

I have just tried to update the fabric API to the latest version, but the problem has not been resolved, so all I can do now is wait
Thank you again for your answer

You can install ViaBackwards on the 1.20.2 Fabric server
