Issue
Management Center ships with a self-signed certificate for its web interface that expires after 182 days.
If you do not use your own CA infrastructure and want to renew the certificate or want to revert from a broken state, you can recreate a self-signed certificate.
If you need to regenerate Server Certificate Agent Communication, please refer to this article: Fixing FQDN Issues for Management Center Installation and Connectivity
Please refer to this article, how to sign the generated CSR via an internal CA:
Creating a CSR in Management Center and Signing with CA
Solution
SSH root access to Management Center is required for this solution.
To do so log in using SSH and execute:
sudo openssl req -new -newkey rsa:4096 -days 182 -nodes -x509 -subj "/O=Nextron Systems GmbH/CN=$(hostname --fqdn)" -keyout /etc/asgard-management-center/server.key -out /etc/asgard-management-center/server.pem
You need to restart Management Center in order for the changes to take effect.
sudo systemctl restart asgard-management-center
