i’d like to monitor a SaaS’ providers website which is hostet on AWS.
Upon setting up the “Check HTTP service” i noticed that the URL is always delivered not by the provider but by Cloudflare.
So i get the following results:
-SSL Cert check only works when disabling SNI (because hostname FQDN does not match the delivered Cloudflare cert)
-URL check results in an " HTTP/1.1 400 Bad Request" if only port 443 is checked, but thats also an answer from Cloudflare. If “Use SSL” is enabled, Checkmk reports “CRITICAL - Cannot make SSL connection.” - whether SNI is enabled or not.
Is there a possibility to make the check behave like the browser?
