Hi, I never had this problem so it was strange for me because I am very careful to add the same version and the same mods, but it gave this error (Mismatched mod channel list), I checked my mod folder and the mods added on the server and are exactly the same, so I don't understand what the problem is.
This is my log file: https://mclo.gs/Ak9YZxg
there are also prints of my mods folder and the aternos folder in the attachments
