After recently upgrading my munin machines to 2.0.11 from 2.0.4 I noticed that munin no longer updates stats when connecting over TLS and instead gives errors like: ... [ERROR] Error in node communication with rama/127.0.0.1:4949: [FATAL] Socket read from rama failed. Terminating process. at /usr/lib/perl5/vendor_perl/5.16.1/Munin/Master/UpdateWorker.pm line 394. ... In order to reproduce simply create a pem cert in /etc/munin/server.pem, add the following in munin.conf and munin-node.conf: tls enabled tls_verify_certificate no tls_private_key /etc/munin/server.pem tls_certificate /etc/munin/server.pem and run munin-cron --debug. The bug seems to be the one reported here[1] and fixed[2] for version 2.0.12 so a version bump would solve this issue. I manually applied the fix and it is indeed working as expected.
