I have upgraded to 2.3 raw (from 2.2) and am trying the new http checks. I have a number of sites that I check and are working properly, and 2 sites that are giving me this error. I can go to the site in the url and it works properly, and I have tried pretty much every option I can think of to troubleshoot this (http version, tls version, redirect follow). I tried running it manually from command line, but I don’t see anything relating to this check, all other checks give success.
Can anyone please help me?
CMK version: 2.3OS version: ubuntu server 22.04
Error message:
Output of “cmk --debug -vvn hostname”: (If it is a problem with checks or plugins)
I just noticed this in nagios.log related to the check, but have no idea what that means.
livestatus: Timeperiod cache not updated, there are no timeperiods (yet)

Well, that is an internal error no one expected.
I just forwarded it to the colleague who oversees development of the check. Could you – if properly advised in details – run the check in CLI? Maybe with strace or the like. My colleague will have more details on debugging.
Thank you for reporting!
I’d be happy to run manually, but would need help with syntax…

Creating the command line is basically the second step and the beginning of the third step taken from this article. Debugging old and new checks is the same:
Okay, that livestatus error may not be related, looks like its an existing issue (from another support thread).
You can see the exact command in the “Service check command” of the service check. You can also paste the entire command here and that should be sufficient as well
This is the service check command as listed…
check_mk_active-httpv2!–url https://www.xxxx.com
On a side note, I don’t know that this is a TLS issue. I forced the old http check to use tls1.2 and it still works, but when I do the same on the new check, it still fails.

The rest of the linked blog is irrelevant. In your case, the command to run is
$HOME/lib/nagios/plugins/check_httpv2 --url https://www.xxxx.com
Give it a try!
error sending request for url (https://xxxx.com ): http2 error: stream error received: unexpected internal error encountered (?)https://xxxx.com ): http2 error: stream error received: unexpected internal error encountered (?)
Thank for for the quick attention by the way!

Could you please provide me with
echo $?
immediately after calling check_httpv2?

I can send you the url if there is a way to do it privately.

The “3” suffices for now. One of us will contact you tomorrow, thanks! I assume, we need the URL, but do so privately and only if inevitable.

Update: @chauhan_sudhir just pointed me on adding --debug-content -vv to give more information at what point the call fails.
Here you go, hope this helps:

This was resolved by changing the user agent string to “check_http”
