Problem Description

Issue

i uploaded the modded minecraft server which has been running locally for the last couple months. it spun up, but the modlist was incomplete. i attempted to to add the missing mods from my local files. the server then refused to start stating invalid client error. i then attempted to replace the config file & the mod file per your help page. It didn’t work thus I am contacting yall. if I could get some help it would be greatly appreciated.

Reproduction Steps

  • added the mods the client said were missing
  • replaced the config file
  • atttempted to search google no help
