Troubleshooting

**CMK version:Checkmk Free Edition 2.1.0p7
OS version: RedHat 7.9

Error message:

AgentUpdate: last_check None last_update None aghash None pending_hash None update_url https://checkmk.famous-supply.com/Corp/check_mk error The agent updater is not registered at the deployment server

I installed the Baked and Signed Agent from our Demo CheckMK server appliance on our Redhat 7.9 server and I have the above error warning and cannot seem to successfully run

cmk-update-agent register

2022-08-07 12:34:22,679 ERROR: HTTPSConnectionPool(host=, port=443): Max retries exceeded with url: /Corp/check_mk/login.py (Caused by SSLError(SSLError(“bad handshake: Error([(‘SSL routines’, ‘tls_process_server_certificate’, ‘certificate verify failed’)])”)))

we are using a wildcard cert for the appliance. Not sure if I need to install that on the client due to the fact it is a valid cert just issued earlier this year.

Hi.

You need to use the optin “-x” (insecure) if you have self-sign certificates in use. Yoiu can find this options by running “cmk-update-agent register --help” . Please try this.
