Problems checking external website

Hi,

i wanted to monitor a external website and still run into trouble - config is set like:

but i still get:

Output of check plugin CRITICAL - Cannot make SSL connection.
Long output of check plugin (multiline) 140411882936128:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:…/ssl/record/ssl3_record.c:331:

Is there any idea what i do wrong ?

Hallo,
please describe your system checkmk is installed on.
You ve direct internet access or are you checking from behind a proxy?

What’s the hostname to which this rule applies?

You cannot create a rule for the host, say, www.bing.com and then set the virtual host to google.de. This will result in an HTTP request to www.bing.com with the HTTP header Host: set to google.de. Maybe www.bing.com doesn’t like the TLS settings?

Hi,

no direct access (too bad) routing is via corp. lan -> proxy -> internet.

I managed to get the monitoring running via the Classical active checks "./check_http -I -p -H www.stadtwerke-husum.de -S -j CONNECT

but of course the new way / plugin would be more awesome

Something like this to try on, Can you key in the desired values and show us the output:

./check_http -I <your_Proxy_Host> -p <your_Proxy_Port> -b 'proxy_username:proxy_password' -H <FQDN> -u <RELATIVE-URI> -S -j CONNECT -e <string to expect in server response>

In order to achieve it using the Host & Service Parameters WATO module >> Active Checks, maybe something like this to get started:
