I just noticed I was running not only my Nextcloud, but also my Matrix and Fediverse (this one) servers with #TLS1.3 only by accident 😮
I thought that would lead to massive compatibility issues. And maybe this setting is related to some issues I had. But amount of complaints is surprisingly low.

“Running code” is distinguishing characteristic of how Internet standards like #TLS1.3 and #QUIC are developed, which is why Ericsson has made a 3-year commitment to support events like the #IETFHackathon, becoming the 1st multi-year, gold-level sponsor:

HTTPS funktioniert im Internet Explorer trotz installierter CA nicht. Kein Webserver unterstützt vermutlich mehr #SSL oder #TLS1.0.
