A Safari 16.0 user complained that Confluence's editor was totally broken, with the generic error "The editor didn't load this time. The connection timed out":
These two lines appear repeatedly in the Developer console:
The editor worked fine for this user in Chrome - just Safari is broken.
I had recently modernized my Apache webserver TLS settings:
Safari 16.0 and 16.1 (latest as of ) seems to support TLSv1.3 just fine, except for when opening a websocket connection. Then (and only then) Safari tries to use TLSv1.2:
If TLSv1.2 is disabled, as in my super-modern config, you get hangs and editor unhappiness.
Seems a few other people experienced this problem with Safari websockets too.
So much for the bleeding edge.
