[][] Browser URL with ':<port>' suffix fails as invalid, i.e. non-standard port used https://<host>:<port> where port is e.g. 1443

Does this problem happen with the domain in DNS, or only with domains in the /etc/hosts file?

I have 2 subdomains with regular ports not in DNS, one I can use with http, the other not. Both are on the same domain, IP, webserver and the only change in httpd_vhost.conf is the name. Neither works with https. All failures have the same error as shown above. I used a new browser profile in /home/nemo/.local/share/org.sailfishos/browser, with the same results.

.spdns.de is a dyndns solution. so the url above is resolved by dns.

With native Jolla Browser and Ielig Web I can reach http://server.domain.local/ but not https://server.domain.local/, error messages as above. Host is defined in /etc/hosts. Firefox can reach both (host file mounted in container). Tested on 4.0 and 4.1.
