I installed mailcow on Centos 8 host running on ESX 6.7. I forwared ports, sorted DNS records to external IP.
I set selinux to permissive
I also disabled IPV6 because currently not present (need to sort out with ISP) using official guide.
After docker-compose up -d I get 502 error and when i check logs i get:
Could not connect to Redis at redis:6379: Host is unreachable
Any ideas? How do I troubleshoot this?
Also I yesterday I had same error when I restored my test mailcow from Hetzner to esx but I attributed this to hostname, ports, DNS not being taken care off.
