Getting an error about read-write overflow whenever I try to join the server I'm hosting

Hello, I'm currently trying to get a modded server to run (using my own modpack) and I've been unable to join. In this case, I keep getting the error "internal exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException: readerIndex(9) + length(4) exceeds writerIndex(9): PooledUnsafeDirectByteBuff(ridx: 9, widx: 9, cap 9/10)" or some variation of it (length and reader index change fairly frequently). I've tried removing mods, changing mods, changing configs, etc. 

If anyone has any help, that would be great

Also, here are the logs for both the client and server

That error means one of your mods has broken networking (usually a broken custom recipe since this is at login).

The log message does not say which mod is causing the problem for this kind of error.

Probably the only way you will find the problem is to experiment with removing mods.

Backup your world before removing mods.

 

But here's all the bug reports on github with an error similar to yours.

https://github.com/search?q=readerIndex(9)+%2B+length(4)+exceeds+writerIndex(9)&type=issues

Maybe one of them matches a mod you have, or one of the bug reports points to another mod causing the problem?

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com  You should also read the support forum sticky post.

Awesome, thanks for the help! I've been removing and re-adding mods for the past few days with little luck, I've got a modlist here if you're willing to look through it. This is the client list (I've taken all the client side mods out of the server list)

      REVIEW OF THE BEST BITCOIN RECOVERY TEAM - MUYERN TRUST HACKER

      By andreygagloev · Posted

      When I first heard about Bitcoin back in 2018, I was skeptical. The idea of a decentralized, digital currency seemed too good to be true. But I was intrigued as I learned more about the technology behind it and its potential. I started small, investing just a few hundred dollars, dipping my toes into the cryptocurrency waters. At first, it was exhilarating to watch the value of my investment grow exponentially. I felt like I was part of the future, an early adopter of this revolutionary new asset. But that euphoria was short-lived. One day, I logged into my digital wallet only to find it empty - my Bitcoin had vanished without a trace. It turned out that the online exchange I had trusted had been hacked, and my funds were stolen. I was devastated, both financially and emotionally. All the potential I had seen in Bitcoin was tainted by the harsh reality that with decentralization came a lack of regulation and oversight. My hard-earned money was gone, lost to the ether of the digital world. This experience taught me a painful lesson about the price of trust in the uncharted territory of cryptocurrency. While the technology holds incredible promise, the risks can be catastrophic if you don't approach it with extreme caution. My Bitcoin investment gamble had failed, and I was left to pick up the pieces, wiser but poorer for having placed my faith in the wrong hands. My sincere appreciation goes to MUYERN TRUST HACKER. You are my hero in recovering my lost funds. Send a direct m a i l ( muyerntrusted ( @ ) mail-me ( . )c o m ) or message on whats app : + 1 ( 4-4-0 ) ( 3 -3 -5 ) ( 0-2-0-5 )

      corail tombstone fire crash

      You could try posting a log (if there is no log at all, it may be the launcher you are using, the FAQ may have info on how to enable the log) as described in the FAQ, however this will probably need to be reported to/remedied by the mod author.

      corail tombstone fire crash

      By belzabel · Posted

      So me and a couple of friends are playing with a shitpost mod pack and one of the mods in the pack is corail tombstone and for some reason there is a problem with it, where on death to fire the player will get kicked out of the server and the tombstone will not spawn basically deleting an entire inventory, it doesn't matter what type of fire it is, whether it's from vanilla fire/lava, or from modded fire like ice&fire/lycanites and it's common enough to where everyone on the server has experienced at least once or twice and it doesn't give any crash log. a solution to this would be much appreciated thank you!
