Hi Leif,

I recently has the same problem and the solution was to put sni on for that host.

I couldn't get it to work in hosts.cfg, don't know what I was doing wrong, so I added --sni=on to the CMD for xymonnet in tasks.cfg.

Regards

Jeremy

Subject: [Xymon] SSL problems with xymon

Recently I got an error with a perfectly valid certificate in xymon.

Xymon reports


red Fri Nov 22 09:50:20 2019: SSL error

red https://www.su.dk/ - SSL error

Seconds: 0.261158000

Trying  to access the site using firefox from Xymon server doesn’t report any error:

[cid:image001.png at 01D5A123.DF366930]

 Testing the certificate using openssl doesn't look right:

echo| openssl s_client -connect www.su.dk:443<http://www.su.dk:443>

Testing other sites using the same method works fine for other sites.

What can I do to solve this problem? How do I proceed?
If I'm missing some information - pease let med know.
