[Xymon] SSL problems with xymon

[Leif Sommerdal]

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:

 Testing the certificate using openssl doesn't look right:


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

CONNECTED(00000003)
write:errno=104

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.





Med venlig hilsen/Kind Regards
