Trashing us publicly for trying to help you doesn't make any sense. You told us you have had up to 30 agents running and said it was great that it's free.
As an admin yourself, surely you can appreciate the complexity of this problem. Even as a free member, we are still committed to helping because we want to find and solve the problem.
The problem is not widespread. If it was, we would be hearing about it a lot but we aren't. You are running 2016 servers and it's quite the task to have a single software that runs across all Windows versions.
Losing track is easy because it's a very long thread, and we've made other updates in some of the releases. The dev told me it was fixed in 1.75 but the log you sent us was 1.77 so clearly there is simply something that got out of sync.
If the agent is not working for you, we do not know why. I can tell you that the Windows dev has been working on yet another release to try and improve the fixes recently made but I don't know if that will solve why only some of your agents are not working right.
I'll reach out again to try and find out what he meant by pointing out 1.75 as being fixed.
