"secure connection failed" message not useful

[jficz]

Some sites produce a "secure connection failed" message (see image) even though other browsers (including Mull desktop counterparts like Librewolf) have no issue with the site.

The message says "contact website owner" but it doesn't say anything useful about the actual problem and reporting such issue with the (lack of) available information would be a waste of time of both the reporter and the site admin at best.

The error message should point to what the issue is, otherwise it's useless, especially in respect to Mull's buffed security which possibly introduces more corner cases.

This is an upstream Fenix issue.

You can use "Request desktop site" to maybe see a better message.

As for the actual error, try one of these workarounds: https://divestos.org/pages/broken#mull

given how many possible causes Mull adds, it might be worth it to patch the message on Mull side. I'd bet upstream will have no particular interest in "fixing" this issue because their set of problems that may cause the message is likely much smaller and more obvious. I can try tho...
