Webmail 404

[jecjackal]

Hi Guys,

I followed the Docker Compose setup instructions, and I cannot access http://localhost/webmail. My goal is to eventually run this email server behind my own reverse proxy, but for now I am trying to stand it up under localhost. Would someone mind helping me out?

When I make the request to http://localhost/webmail, the request makes it to the front container, but the webmail container cannot find /webmail. Here is a log from the webmail container from one of my attempts:

172.20.0.7 - - [25/Jul/2018:16:08:51 +0000] "GET /webmail/ HTTP/1.0" 404 459 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36"

Here is my .env file:

# these few settings must however be configured before starting the mail
# server and require a restart upon change.

here is my docker compose file. I made a change to use the no SSL nginx, as this will already be sitting behind my reverse proxy, which provides TLS.

Thank you for the help,

The nginx-no-https has been deprecated since 1.5, you should only use the nginx front container which supports multiple TLS flavors. If you wish to setup your own reverse proxy and TLS endpoint, you could use the notls flavor which disables TLS altogether.

That was it. Thank you so much @kaiyou.
