cant join the server due to this mod

latest.log

Handshake crash because of this mod which is involved in the Prominence 2 modpack;
owo version is 1.20.1 /0.11.2.jar
Reinstalled the mod, reinstalled client, no succes.

This is not a crash, it is an error. You are missing Mythic Metals on your client

I reinstalled the mod specifically and the whole modpack and client again. So there wont be anything wrong with the client.
but i found the problem, the server was configured some mods to match their server hardware. Since i could join other servers/official prom2 server but not theirs. Still thank you for the time to respond!

A regular log contains more info than this. If you are able to reproduce this issue, please provide a full log. Fabric always logs what mods you are using first thing in the file, which usually helps pointing to the issue.
As Blodgharm mentioned, a handshake error usually occurs whenever you have mismatching mods between your client and your server. Make sure that you are using the same on both ends.

the log file is literally right there in my message

also i gave up on aternos

Without more information about the given modpack/modlist combined with version info about Minecraft or owolib we can not assist with the issue. A log file and/or the crash log is required to further help.
