10 years ago, someone setup for me a Raspberry Pi programmed to run my sprinkler system. Worked well for 10 years. Then, 2 days ago, the certificate they setup to allow remote login expired... As of now, the person that set it up is not responding to my attempts to contact them.
The only access that I have is using the domain name that was setup via No-IP, which goes right into the sprinkler software (Open Sprinkler), which it won't do because the certificate has expired.
My brief research shows that once a certificate expires, you have to make a new one, it cannot be renewed. And, of course, somehow the server software that is being used needs to know of the new certificate.
I am reasonably proficient with Windows, Command Prompt, etc, but have no knowledge about the Raspberry Pi. Looking for any insight / ideas that to move forward, i.e. how to connect to the Pi to find the certificate reference, get it updated, and running again.
Thanks in advance.
