I'm sorry, my English is not very good, so I understand that you don't understand me...
I know how to set up DNS, I use a reverse proxy, but my problem is elsewhere...
I have added aaaa.com and bbbb.com domain in cloudron, cloudron is running on VPS-A and both domains have one public IP address for example 172.22.0.160.
Then I have another VPS-B, on this VPS I have the domains cccc.com, dddd.com, eeee.com, gggg.com... Again they all have one public IP 172.22.0.160, only they run on different ports and none of the domains on VPS II are added in cloudron.
However, when I open the eeee.com domain that runs on VPS-B, I get an error from cloudron:
You are seeing this page because the DNS record of eeee.com is set to this server's IP but Cloudron has no app configured for this domain.
So after installing cloudron all my projects on all VPS are down, even though they have nothing to do with cloudron. I can only get to the web if I specify the domain and port (eeee.com:8444).
Sorry again, hopefully it's more understandable now..
