On FP2 version 3.4.0 (community port) it’s the same behaviour.
I also setup a Website without ssl (port 4080) - but this is not helpfully because the the jolla Webbrowser automatically replace the http with https - the same a firefox does (this is stupid - and could not work on URLs with ‘:port’ because ssl always use an other port as nonssl …).
Google chrome did a better job here.
