Possible Fixes

Yes

Modpack Version

0.2.55

What happened?

After update of dedicated server, joining to server is no longer possible. -> either "Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException: Index 26 out of bounds for length 5" or timeout.
Restoring Server to 0.2.54 and also client, login possible with no issues. Again Update -> Same Problem

Wondering about this one as well.

Could you please update to 0.2.56 and see if this fixes your issue? There was apparently an issue with Gtceu that should be fixed.

Yes, that has fixed the problem, Thank You very much and thanks for the great mod!
