Hey, there is already an PR (#6606) for this exact same change and it got everything working but need minor changes.

We will wait some more time for that PR author to implement the requested change, if they didn't respond then we can consider this PR.

She probably thought its a UI related PR after reading the first part of the Title "Remove unused svg" xD

Next time please start the title like fix(service):

BTW, if this PR (#6606) is not changed and we end up using mine, i'll probably change the Cert system, which can make this template click and deploy...

For now you have to make changes in the server proxy and compose file... That's too complicated if we can just attach let'sencrypt... But Idk if this works for everyone (idk how those work...)
