Root http https route to webtop

I see in the docs how to change the public url of webtop, but is there a way to change it to the root.
So that office.mydomain.com points to office.mydomain/webtop.
I can do it with the virtualhost in nextcloud, but I want to do it for webtop as that is our main landing page, is that possible?
I do not have WebServer installed, and don’t want to.

You can try use Reverse Proxy and configure a Virtual Host in Reverse Proxy. “https://office.mydomain.com” points to “https://IPADDRESS/webtop”.
Try it, I don’t know if it works.

What is the problem to install WebServer?

Nothing, just unneeded resourc. I don’t need it, and I don’t think it solves this isssue. Unless it does, I am not really sure.
I tried this,
“https://office.mydomain.com” points to “https://IPADDRESS/webtop”.
Doesn’t work in reverse, but if I set it up as a virtualhost then the redirect works. But, then for some reason, mydomain.com/nextcloud also goes to webtop. Not sure what is going on there.

With reverse what kind of error do u receive? Set it as reverse virtual host and force HTTPS.

WebTop has no builtin support for virtual host support.

Actually you already have it without the UI configuration part.
You could manually create a new file inside /etc/http/conf.d with a virtualhost hosting the WebTop applications. The /etc/httpd/conf.d/webtop.conf is a good starting point.
