Card pop-ups do not work - missing port in URL - wekan docker

Hi, I installed Wekan via Docker and it is accessible via port 8080. All works fine so far, but whenever I click on a card or a link to a card, I get an error page.

Not Found
The requested URL /b/376rJEBudZNWRRvf3/welcome-board/cemsb5uBfbgYya788 was not found on this server.

This is because the :8080 is missing in the URL to that card. When I log in, I am on http://<ipaddress>:8080/b/376rJEBudZNWRRvf3/welcome-board. However, clicking on a card invokes http://<ipaddress>/b/376rJEBudZNWRRvf3/welcome-board/cemsb5uBfbgYya788 which results in the above error. If I manually add :8080 to the ipaddress all is fine.

Is this a bug or have I misconfigured something?

Thanks for your help.

For people running the snap and not the docker version -

# as per wekan.help
snap set wekan root-url='http://192.168.1.68:8080'

Am kinda surprised I had to do this, especially since the port is already decided, but eh, gonna leave it here for those who ran into this before checking the help page.

Absolute URLs such as the above card URL are generated from the ROOT_URL environment variable. Adding the following parameter to the docker CLI launcher: -e ROOT_URL=http://<ipaddress>:8080" should fix your issue.
