I have a similarly problem like @hunv in Too many Redirects when accessing Roundcube

I setup a virtual host “host.domain” to access my server from the internet. I set the “ssl is required checkbox” to true. When I try to connect to my server via https://host.domain a test page is viewed properly but when I connect to https://host.domain/webmail my site is redirected to http://host.domain/webmail. After two or three tries and always putting https in front of the url its working.

when I do curl -L -v -k https://host.domain/webmail from outside my lokal net I get:

/Users/test==> curl -L -v -k https://host.domain/webmail

400 Bad Request

Bad Request

Your browser sent a request that this server could not understand.
Reason: You're speaking plain HTTP to an SSL-enabled server port.
Instead use the HTTPS scheme to access this URL, please.

* Curl_http_done: called premature == 0 * Closing connection 1

The same is happening with every app like nextcloud, dokuwiki, …
When I issue the curl command from the server itself it´s working.

Any ideas?
