*RESOLVED*
Solution:
My friend uploaded version 1.15.3 to DropBox and I replaced the zip file in my mod folder.
Problem:
When I visit the Forge Mods menu from the title screen I see that I have TwilightForest version 1.15.4
When I try to log onto my friend's server I get this error message stating that I need an earlier version, 1.15.3.
