When Playing on the server it seems to randomly at some points when entering certain locations on the map, timeout then proceed to crash. Can't seem to see any issues myself as to why. I will attatch the crash log.

Thanks for your time,

I think it is related to this issue.
iron431/irons-spells-n-spellbooks#284

since current version of the mod is 2.2.0, and the bug fixed in 2.2.1, so just wait for the ATM updates.

I was also having this issue and can confirm that version 2.2.1 resolved the issue for me.
