My problem is: Unknown InResponseTo fresh install v6 using v4 local config · Issue #15708 · mautic/mautic · GitHub

I’m getting the same error that was fixed in version 5.*

There’s nothing in the logs and I’m not even sure where to begin tracing the cause of the problem

Steps I have tried to fix the problem: Accoring to the git report this was already patched v5 but I can’t get it to work
