Good Evening,

I recently spun up an iRedMail instance and I everything is working as expected. However I can not access RoundCube Webmail from outside my network. If I access it via local IP then it works as you would think. However when I try to access it from a URL I assigned it from my domain I get a 503.

I run multiple services so I use Apache2 to act as a Virtualhost reverse proxy. I set up a virtualhost in my Apache2 VM and pointed it at iRedMail assigned it a Let's Encrypt cert and nothing.

I've tried commenting out SSL in Nginx and it breaks everything. I tried to remove the cert the install gave me and it also breaks everything.

Any ideas?

Thanks for your time.
