Nagios Support Forum

BINGO! One I set the the certs in /usr/local/nagios/libexec/check_nagiosxiserver.ph
with
curl_setopt($ch, CURLOPT_SSLCERT, '/usr/local/nagiosxi/html/yourclientcert.crt');
curl_setopt($ch, CURLOPT_SSLKEY, '/usr/local/nagiosxi/html/youclientcertkey_nopass.key');
$response = curl_exec($ch);

using my certs and forced a check it WORKED! I had all of these set and working for 6-7 months then one day all of these settings were reset to default. We havent upgraded... this might remain a mystery.

Thank you guys so very much!

Unsure how the plugin could have been reverted without an upgrade, did you upgrade any of the components/wizards at all through the web interface (Admin > Manage Components OR Admin > Manage Config Wizards)?

XI really wasn't designed with client-certificates in mind, you were the first person that I worked with to get it setup, I did create a feature request for that as well but there hasn't been any movement on it as of yet:

Hi Sean I just realized it was you who I was chatting with. Seem like each day I get a new tech. I can say that I didnt change it and that these changes are so specific that no one on my team would know where to find these files. I backed up all of the .php files before I changed them and the back files were even deleted. I truly have no idea how this happened but I will back them up to remote storage for safe keeping.

Sound good, glad it's working though! Are we okay to lock this and mark it as resolved or do you have any other related questions?

Indeed! Thank you!
