Hi Daniel, thanks for the report. Such things always smell a bit like "intentionally done for security reasons", but then complexity sometimes is so high that one doesn't directly see what is going on and why. I didn't see anything suspicious in your logs, but the fact that it works for the other sites you listed makes me expect a subtle configuration difference.
I subscribed ubuntu-security if this behavior is in any way known or expected to let us know about it. Since "ppa:ondrej/apache2" isn't really supported, you with your existing setup quickly check if the official 2.4.41-1ubuntu1 in Ubuntu 19.10 is affected as well? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848577 Title: Apache2 2.4.41 Causes TLSv1.3 Errors and Disconnects To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apache2/+bug/1848577/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
