Ingeborg,
    HTTP/2 support is currently not in xymon, including in the 4.4alpha1
development tree.  I did a little testing, and sites like google that
support HTTP/2 still pass the xymonnet checks as seen below:

$ curl --head https://www.google.com | head -1
HTTP/2 200
$ grep google ~/server/etc/hosts.cfg
0.0.0.0         www.google.com          # conn https://www.google.com/
$ ~/server/bin/xymonnet --no-update www.google.com |grep -B2 HTTP
&green https://www.google.com/ - OK


HTTP/1.1 200 OK
$ ~/server/bin/xymonnet --no-update www.google.com |grep -i ssl
status+30 www,google,com.sslcert green Wed Nov  1 08:38:21 2023
&green SSL certificate for https://www.google.com/ expires in 2252 days


Perhaps the website you are testing is configured to support HTTP/2 and not
support HTTP/1?  Try running the xymonnet command manually similar to what
I did here.

I have a webserver which works ok when you visit it in a browser or when
you
use curl, but Xymon http test shows "SSL error". Tests with "openssl
s_client"
from the command line works as expected.

Could the culprit be that xymonnet does not support HTTP/2 ?
