Is there anything between your XO and the pool master, like NAT, a firewall or a VPN?
No, XO is running on master (twinstor)
Both hosts connected to the same switch
the remote is 2 swithes away
same switches as my "production" pool

Does it fail every run, or intermittently?
Only run scheduled once, manually once.
I will increase the schedule to more than once a day
More answers to come later.
