I wear a armor in Create Protection Pixel , then I can't join server. I have tried to remove this item by NBTExplorer. It's work. But when I try again to wear the armor. I can't join again . But single player game didn't have this problem. I think it might have something about server-side mod running on Sinytra Connector. Client return "internal server error".

Please read the issue template more carefully. For modpack related issues, use the support channel on our discord server.

Before reporting, please ensure that:

• You've installed a minimal set of mods required to reproduce the issue.
  Issues with modpacks and excessive amount of mods will not be accepted, as they take a long time to diagnose.
  Knowing which mods are causing problems allows us to focus on fixing the issue as soon as possible.
  If you're unsure which mods might be at fault, try using binary search - removing half of installed mods
  repeatedly until the faulty mod is found.

To upload logs, use an external paste site, such as Github Gist (recommended), Ubuntu Pastebin or Pastebin
