If I look into the console of the server after I want to start it, what does that mean and what can I do about it?
[Server thread / WARN] [FML]: Mod mekanismgenerators is missing the required element 'version' and a version.properties file could not be found. Falling back to metadata version 1.12.2-9.8.3.390>
You could remove the MOD as it will not try to load it and will not fail.
Are there any other problems? I can't see an error there. Would be helpful if you could post the whole log
The mod version used is not compatible with the server. Try another mod version.
