I had thought this may have been related to some recent stat moves, but it doesn’t seem to be.

This appears to be a bug where alternate_node_list isn’t set potentially when all node are down.

Is this issue persistent (i.e. will it work if you restart AMC)?

Erik_Parienty · June 9, 2016, 5:32pm

Still the same. I tryed do downgrade back to the old version but the same problem.

kporter · June 9, 2016, 5:42pm

Appears the bug was introduced in AMC 3.6.8, I suspect you won’t need the “TOOLS-557 - Support private to public IP mapping.”

Recommend downgrading to 3.6.6 till this issue can be resolved, you can find a link to the download here:
