Protocol mismatch

[PeterW]

I have a program running on the server that creates tokens, moves users, assigns groups, etc.

It seems this is causing many errors in the client log

How can this happen with standard server query?

Depending on when you created the program running on your Server you might not have covered changes that happened with the latest betas.

You could try to manually execute the Commands to see the exact error message that appears for the commands and on which commands they happen. That would help in determining whats going wrong...
