I received an error message of expired SSL/TLS certificate when logging in to my Webmin server. I am using Let’s Encrypt to manage and automatically renew my TLS certificates. I checked my certificates and they had been updated and were current, however Webmin was displaying an older expired certificate. The old certificate must have been stored in memory and not seeing the new updated certificate. I restarted the Webmin service and it now is using the new updated certificate. Here is the command to restart Webmin.
