I get this error on Rust Public Test Branch but only when i try to connect to Building servers not on target practice servers.


I have tried everything formatting ps4 to factory settings n everything else on youtube or google.

I also have that problem, I have already done everything and nothing helps and I have reinstalled all my game and after 3 days it has the wrong code again.
