Quick Start tutorial links give "Your Internet connection is blocked"

[Tom Goddard]

On macOS 12.3 my development ChimeraX builds with Qt 6 and unsigned give the message "Your internet access is blocked" in the browser when I click on any command links or on external https links. ChimeraX 1.3 does not have this problem. The internet connection is working and new uncached PDB files can be fetched with the open command. Also if I load a tutorial on the web (e.g. proteasome tutorial) using ChimeraX Help / Tutorials, all of the links in that web hosted tutorial work correctly. So it appears links in the Qt 6 html help browser don't work only if the source file containing the link is a local file.

I also got the same "Your internet access is blocked" clicking on the file history thumbnails on my work Mac (Intel), but not my home laptop Mac (ARM64).

Links like help:user/commands/open.html from the log work.

Since the problem is both on my home network and at UCSF (although slightly different file history behavior), it does not seem to be related to the internet connectivity.

Trying the daily build which uses Qt 6 but is signed does not have this problem. ChimeraX 1.3 which is signed with Qt 5 does not have this problem. Need to test if a Qt 5 unsigned build has the problem.
