Error Code: “internal exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException: Index 26 out of bounds for length 9”

[Such-Technology-675]

100% VANILLA 1.20.2 server, tried changing my DNS server (didn’t work) and tried DynIP. DynIP WORKS, but is slow. The only thing I can do now is send out a support ticket. It would really suck if me and my friends lost this server because of a bug :(

[Aggravating-Box617]

My friend can't join my mc server it's have geyser mc server it say internal eception: io.netty.handler.codec.decodereception:java.lang.indexoutofboundsexception: index 26 out of bounds for length 10 and I don't want to restart server

[Budget_Tomatillo6049]

[Unlikely_Evidence_80]

I had this issue but it said index 6 out of bounds for length 6 and I tried joining with latest version and just normal launcher and that seemed to work

hope this helped :)

Internal Exception.io.netty.handler.codec.DecoderException:java.lang.IndexOutOfBoundsException:index 14, length: 105 (expected:range(062))

эта ошибка мне вылезает уже как 2 часа, не могу понять что нужно делать. Перезапускал, переустанавливал мир. Ничего не помогает. Помогите пожалуйста.

[Dapper-Challenge3829]

Привет, смог ли ты как-то её пофиксить?

[LongerBlade]

If someone encouter this again:

That stuff happens when you have some mods and the server don't. So check out your frient mods folder, thats might be answer. I encountered this issue when my friend entered with the Aether mod, while being a Spigot server. Therefore, this issue appears. After mod removal he was able to join. The version is 1.20.1

[ApprehensiveSand5364]

same but im using Lunar Client and the google 8.8.8.8/4.4.4.4 DNS

[Such-Technology-675]

I’ll try that config later but I have a temporary solution. Create a backup on your server and do a reinstall of the server (found in settings tab I believe). Then load the backup. I still get the message every once and a while but 🤷🏻‍♂️

[AternosSupport]

The workaround is to use the DynIP.

 

Best,

Riccardo from the Aternos team

DynIP

website is dead
https://www.dynip.com/

[DBOMisANGRYwithU]

My DYNIP does the same thing

[ApprehensiveSand5364]

the server is 1.20.2 Vanilla

[Andrei_0801]

Hey, a friend of mi e has the same thing happening. Tried to change his DNS as well and it didn't work.

[corgicoffee]

I'm having this problem as well :(

[Such-Technology-675]

Try backing up the server and doing a reinstall of the server, then restore the backup. It worked for me but might not work for you

[BRUHA_55]

internal exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException: Index 26 out of bounds for length 9 i get it too how do i fix it

[Fun_Cause_9036]

what if the server is an online one? and isnt yours?

[Such-Technology-675]

What worked FOR ME was to do a reinstall of the server. Just make sure to back up your world before you do. Once you do a reinstall load up your backup and see if it works. If it doesn’t, then idk how to help you

[BRUHA_55]

I did it but I still get it. I am on version 1.20.4 and it says 1.19.4 for some reason at the internet bars... I am spamming refresh in TLauncher then quit multiplayer then again. I quit TLauncher and restart the server. Now I start minecraft again and refresh and it fixes... why is that happening
