Hello,I also have this problem on a medium icinga2 installation, about 50 hosts and 1 master. Every day almost, clients are intermittently losing the connection to the master, it very annoying and seriously affecting the useability of this package on buster.
Disabling TLS 1.3 system-wide is not a workaround that we can deploy. I don't think anyone should be doing that, either...
Would it be possible to publish a backport to buster to fix this? Thanks.
