Solved Having problems joining my friends sever

[Dubleu]

My Version of FTB Revelation 3.3.0 is not modified. When I was playing yesterday my game suddenly crashed and this error message popped up when I tried to rejoin the sever after a restart.

After reinstalling severalversion of the modpack the error message still pops up.
After trying the newer version of the modpack (Exchanging a few mods for older versions to be able to play on the sever namely AE2WTLib-1.12.2-1.0.34, DankNull-1.12.2-1.7.101,p455w0rdslib-1.12.2-2.3.16, refinedstorage-1.6.16, refinedstorageaddons-0.4.5 and WirelessCraftingTerminal-1.12.2-3.12.97 for their older counterparts AE2WTLib-1.12.2-1.0.30, DankNull-1.12.2-1.6.77, p455w0rdslib-1.12.2-2.2.156, refinedstorage-1.6.15, refinedstorageaddons-0.4.4 and WirelessCraftingTerminal-1.12.2-3.12.93 respectively) The error message prevails.
Before this error message the game stated "Fatally missing registry entries"

Edit: After completely deleting my config folder I still wasnt able to join the sever ( no suprise here ) suprising was however that the same error message popped up leaving me to believe that the problem is not within the configs.

Same problem here, in both my personal computer and small server.

It has come to my attention that the problem is due to the holidayIn-Game content and different time zones

After waiting 23 Hours and restarting the Sever it was solved.
I Also tried to reinstall the ModPack again so do that too just to be sure I guess
