Hi,
I have found an issue when trying to monitor imaps and pop3s server

For some strange reason, I can monitor a https web servers (running
nginx or apache) offering TLS 1.3 without this issue but not
imaps/pop3s.
It looks like the https test is different from other ssl/tls tests and
does not have the TLS 1.3 issue
Hello List,
this issue is also discussed in
https://www.mail-archive.com/user-6a19335d3e19@xymon.invalid/msg1804680.html
and
https://salsa.debian.org/debian/xymon/-/merge_requests/1
at least contains an attempt to patch this.
I can also confirm this TLS 1.3 issue for ubuntu (currently 18.4 LTS bionic).
It affects all banner checks in combination with TLS 1.3.
Kind regards,
Lars
