I try to join to my server but it says missmatched mod list, but i have the same version of the mods on my folder
The error message "mismatched mod channel list" tells you that the installed collection of mods is not the same on the server and the players' computer.
You have to make sure that the installed mods are the same on both. (Out of server-side/client-side only mods)
It is not enough to simply have the same mods installed, they must also be installed in the exact same version. Likewise, the version of the mod loader (Fabric/Forge) must be identical.
