I think it's solved now.... I banged my head against the wall for hours last night about this problem.
This morning I recreated the replication task and it the failover task was accepted without issues.
And I have done that a million times last night! I even rebooted both nodes see if that fixes things.
Unfortunately nothing helped, until this morning....
I do have an other problem tho. When I reboot the second node it comes back in a default setup.
I had to shut it down, wait a few minutes and then boot it up again to get it fixed.
This happened to me before
