I have set up a Group Replication. There is one principal source server which I am going to call SourceServer and one MemberA and MemberB servers. I have set up a mesh topology. MemberA and MemberB are in a different site as SourceServer is.
Now my problem is all replications work fine for SourceServer <---> MemberB (both ways), and SourceMember ---> MemberA and MemberB ---> MemberA.
But MemberA doesn't seem to replicate anything to anyone. Which is really strange. I run a test report and it just shows the test incomplete forever (more than one day now).
I created a trivial test replication group between MemberA and MemberB and works fine.
The EventLog seems normal with no strange errors (just some disconnections every few hours but I think it is normal. I see this errors in the other two servers too and they work fine).
