Error when trying to join the server

[flamingironbird]

I'm not sure if this has anything to do with some batteries i placed in my claim last night but they did cause some issues and now when i try to join the server i get this error

Is this something on my end because i have re-installed FTB and the modpack and allocated more memory but nothing seems to change.
thank you for your time

Issue is now resolved. It was something to do with a battery placed in my building. was able to destroy it and it resolved the issue.
