Gregory's Server@Gargron I think I found the issue, which is of course Docker’s fault 😭 It’s externally accessible via IPv6 but it doesn’t have access to outbound IPv6 networks. I need to look into this more, but it appears that Docker Compose v3 actually removed the enable_ipv6 support because Docker doesn’t support IPv6 in Swarm mode (whatever that means).
God I just want this to work, time to dust off the “list of things I need to do to move off of Docker” list.
@ashfurrow If you are OK with downtime, moving off Docker means doing a pg_dump/pg_restore plus maybe copying the dump.rdb from the redis container over. A minimal downtime approach would have you setup a hot standby for Postgres and Redis and then doing a switch-over.
