Hi,
I ran the update.sh script this morning. After that, the stack didn’t start with the following error message:
[+] Running 1/1
✘ Network mailcowdockerized_mailcow-network Error 0.0s
failed to create network mailcowdockerized_mailcow-network: Error response from daemon: invalid pool request: Pool overlaps with other one on this address space
All my networks were set up as expected (I had only the 3 default docker networks bridge,host,none in place, nothing else).
After some research and unsuccessful trial/error runs with the IPv4 address ranges, I got it back working by commenting out the IPv6 subnet section of the mailcow-network in the docker-compose.override.yml. The internal IPV6 network in this section started with: “fd4d:6169”.
After commenting out this section, the mailcow network now got an IPV6 prefix starting with “fd98:d6aa”, no idea where this prefix is being set, so all is working fine (IPv4 and v6).
Hope this helps if somebody gets stuck with the same issue.
