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 01D5A11B.2B073820]
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.
