Yeah, I realized that after posting the screenshot. Really the only important part is that it gets stuck at:
If TP2_LO1_Progress = 10.11 and Is ready for input
When I disable the 'Is ready for input' condition, the peer is able to progress onto and gets stuck at the next condition:
If Peer message Send_... and TP2_LO1_Progress = 10.12
This is the reason why I put the Is ready for input condition there in the first place, to make sure the host is ready to receive and transmit the data.
What is the correct way to use this condition?
Why is there a communication breakdown between the host and the peer?
Everything was working perfectly until a couple days ago. It is super strange because all my older backups are hitting the same issue in the same place.
