Issues with loading the server

[ViperMike2020]

So I've been having the same issue, while trying to load into the stoneblock 2 server. I keep getting the same page, showing that multiple different mods require a different version.....If I can figure out how to, I will post a screenshot of what it's saying.....

Have you tried reinstalling the modpack?

What launcher are you using, also what version do you have. We are currently using version v1.21.1
