Could everyone help me ? I don't know where is my setting wrong. I can't open my web mail page. [upl-image-preview url=https://community.mailcow.email/assets/files/2024-03-26/1711438292-379601-2024-03-26-074634.png] [upl-image-preview url=https://community.mailcow.email/assets/files/2024-03-26/1711438047-40112-2024-03-26-074553.png] [upl-image-preview url=https://community.mailcow.email/assets/files/2024-03-26/1711438047-510277-2024-03-26-074718.png] [upl-image-preview url=https://community.mailcow.email/assets/files/2024-03-26/1711438088-963965-2024-03-25-133640.png]

Leave HTTP_BIND AND HTTPS_BIND empty HTTP_BIND= HTTPS_BIND= Those are for binding to IP addresses

@"[unknown]"#p14299 Thanks for your kind help, but it's not working after motifying. [upl-image-preview url=https://community.mailcow.email/assets/files/2024-03-26/1711447753-933719-image.png]

@"DocFraggle"#p14299 Thanks for your kind helping but it still can't solve the problem after motifying it.

@"nickydream_"#p14302 Did you restart mailcow after changing the config? ``` docker compose down docker compose up -d ```

Did you check if all the containers are running? Did you check the container logs? Did you check your host's firewall if present? Did you check if any other services are running on the ports mailcow needs?

@"DocFraggle"#p14307 Running. No problem here: [upl-image-preview url=https://community.mailcow.email/assets/files/2024-03-26/1711455895-703794-image.png] But It still can't open the mailcow web

> @"DocFraggle"#p14307 Did you check the container logs? Did you check your host’s firewall if present? Did you check if any other services are running on the ports mailcow needs? ☝️

@"DocFraggle"#p14310 Apart from container logs, I checked firewall, not problem here . And nginx is proxying a web and mailcow, but there are in different ports. I had checked they don't have a Port conflict. Where do I check the container logs? I have checked nginx error log. Also normal.

If you connect to localhost:8080 in your nginx reverseproxy config you have to run mailcow on 8080 HTTP_PORT=8080 Red the docs: https://docs.mailcow.email/post_installation/reverse-proxy/r_p/

HELP!!! nginx proxy mailcow!!

DocFraggle

OK, it’s working. But it looks you didn’t setup the DNS records?

> host mikemail.mikelearner.com
Host mikemail.mikelearner.com not found: 3(NXDOMAIN)

I think nginx listen port 80 and according to its name (I have another web that needs nginx to proxy) , send its data to different web/mail. Because in the server, there is only an IP address. Web can do that…

DocFraggle

No, you don’t have an A record for mikemail.mikelearner.com, only for mikelearner.com as far as I can see there.

nickydream_

DocFraggle

So what’s wrong with my DNS records?

DocFraggle

DocFraggle you don’t have an A record for mikemail.mikelearner.com

nickydream_

DocFraggle

So I should delete MX record?

If my record is correct (with MX record ), why can’t I open web. Strange

DocFraggle

No… I’m not familiar with the strange DNS console you pasted above, but you should be able to create a new A record there

mikemail.mikelearner.com has to point to the IP address of your server (A record)

The MX record is correct

You need autodiscover.mikelearner.com and autoconfig.mikelearner.com as well, either another A record with the IP of your server or a CNAME record pointing to mikemail.mikelearner.com

This whole thread is what we call “eine sehr schwere Geburt” in Germany…

DNS solved but

mikemail.mikelearner.com redirected you too many times. Still can’t open page

[unknown]

DocFraggle

Set this in mailcow.conf:

HTTP_BIND=127.0.0.1
HTTP_PORT=8080
HTTPS_BIND=127.0.0.1
HTTPS_PORT=8443

according to https://docs.mailcow.email/post_installation/reverse-proxy/r_p/

nickydream_

DocFraggle

Not useful:

This page isn’t workingmikemail.mikelearner.com redirected you too many times.

DocFraggle

As I’m not running a reverse proxy myself. here’s my last hint, if that doesn’t work you have to ask someone who is actually running mailcow with Nginx reverse proxy.

Create the file docker docker-compose.override.yml in the main directory and put this in:

version: '2.1'
services:
  nginx-mailcow:
    environment:
      - VIRTUAL_HOST=mikemail.mikelearner.com
      - VIRTUAL_PORT=8080
      - LETSENCRYPT_HOST=mikemail.mikelearner.com
      - LETSENCRYPT_EMAIL=letsencryptemail@mikelearner.com

Then restart mailcow and check if it’s working
