Automatic Agent Update Registration Failing with Internal error: 'list' object has no attribute 'update'

No proxy but these are in different datacenters so firewalls are a factor however, the peer servers that registered fine are in the same subnet.

Might still be worthwhile to ask the firewall admins, if they do web application firewalling. Newer firewalls can do that, and we have seen the weirdest effects there.
