-You are using an outdated version of the mod, do not provide the version of the mod you are using, or are using "latest." "Latest" doesn't mean anything to developers, so please avoid using the term and state the specific version, even if it does happen to be the latest release at the time.

Closed due to invalid issue report

I suspect it's because you're using 1.16 which has a bug on servers; this is fixed on 1.17
