Safari redirecting to http instead of https
When using Safari 14.0.3 on Mojave, if I paste https://gramhum.com in the address bar, I am redirected to greatfon.com, but the "https://" part disappears and the query is sent unencrypted via port 80. It is blocked by the firewall, so it fails.
I have to manually retype the URL to make it work. Same thing happens if I click the link inside an HTML file.
The option "Show full website address" is enabled, and if I replace https://gramhum.com with https://greatfon.com, it works.
I have no problem with Firefox and Chrome (these browsers redirect properly to https://greatfon.com).
Solution 1:
I wonder if you may be seeing a feature that was a bit controversial when Apple introduced it, namely, not showing the full website address.
If you go to Safari > Preferences > Advanced
and check "Show full website address." and then once you are on "https://anywebsite.com" just click once in the address field. That should show everything including the http/https string.
Does that solve your issue? If not please edit your question and add some more details so we can assist.
