Submit license usages online not working

CMK version: 2.3.0p6 CEE
OS version: Ubuntu 20.04.6 LTS

Error message: [Error] Could not connect to the license server (https://license.checkmk.com/api/verify). Please retry again later. If this error persists, please contact the Checkmk support. You also need to make sure that your Checkmk can reach the license server. Please check your firewall and proxy settings.

Hello Community

I need your help. I’m trying to upload my license usages online - but get a connection error as written above.

My proxy and firewall are configured right - as far as i can see.
I checked the connection to the checkmk licenses server by sending a curl-request from the shell on my checkmk server as the site-user and received an expected response:

OMD[site]:~$ ccurl -x http://proxy.my.domain:3128 -X POST https://license.checkmk.com/api/verify
The Licensing ID or password you entered is incorrect.
OMD[site]:~$ _

So the server seems to be able to access the license-server.

On the site at Setup > General > Global settings i sat up my proxy at Execution of checks > HTTP proxies - even if this seems to be for checks, not for the licensing.

But i am unable to find any other place to setup my proxy for this connection. Is there anything i’m missing?

Your help in this is appreciated.
Thanks in advance!

We currently have the same problem.
Although there is a global setting for HTTP proxies, it seems that the licensing mechanism does not use this proxy.
There is also nothing else to be found in the documentation.

We have also tried setting the environment variable HTTP_PROXY, HTTPS_PROXY, http_proxy and https_proxy for the respective omd site user. Unfortunately, this does not help either.

Edit: Never mind, after setting the environment variables and an “omd restart” the license transfer works for us.
