Error incheck_http when checking cert expiration

[ajacobs]

Hi

I am in the process of upgrading our nagios servers from debian7 to debian9, and have run into a problem with check_http.

In the old version (2.1.4) the command "check_http -H hostname -S -C 20 --sni" gives a correct answer, but the new version (2.2.1) gives a wrong answer because the server responds with a 403 HTTP response. That is it always returns 1 no matter the expiry of the cert.

Is this a known problem, and is there a workaround ?

Best regards
Allan

Hi @ajacobs,

This sounds like a known issue that has been reported and added to the bug fixes for the next version.

There is the option of downgrading back to 2.1.4 if you need the -C certificate check.

Does this help?
