On first glance, this looks like a version mismatch. Are client and server running the same version of Spectrum?

If there is the same version of the mod as on the server, then a disconnect is provided when connecting to the server

Interestingly, the error states something else as the issue from the screenshot entirely.

java.lang.NoClassDefFoundError: dev/ftb/mods/ftbchunks/data/FTBChunksAPI
	at dev.ftb.mods.ftbxmodcompat.fabric.ftbchunks.commonprot.FTBChunksProtectionProvider.canBreakBlock(FTBChunksProtectionProvider.java:85)

that rings a bell. See: #388 (comment)

TL;DR: Update FTB chunks.
