@olivierlambert FYI turned out to be a networking issue that had nothing to do with the server itself. I'm still getting to the bottom of what exactly the cause was, and will update here once I do just in case someone else runs into this. Thanks again. And thanks for the awesome software. ! -Rob

Was searching around to see how I could enable with more current version of Netdata (with cloud support) - did this effort go stale?

thanks

@olivierlambert Hi. Thanks for replying.

Single host.

In the screenshot, it's the host called Kipp. I can add it, but then it times out and says it connection failed.

After an ungraceful shutdown, server can no longer connect. I have removed and re-added under settings\servers, and it will add but then time out. Server still connects fine to XCP-ng Center (thank goodness).

This is all I'm seeing in /var/log/syslog:

Update. Also seeing a lot of these:

That UUID being referenced is the server that will no longer connect.
