We currently are using the PFC200 with HMI functionality provided via webvisu. I would like the webvisu pages to be served over HTTPS. Everything is set-up and working, but I worry about certficate expiry. Our product once installed can remain in place for 15+ years. At present, the server is using a certifiate provided by Wago, which is due to expire on 1 Feb 2036. I tried to add a self-signed CA key / crt pair via the WBM, but this is not being picked up by the system. Any advice greatly appreciated.
Hello, the WBM CA/Key is only for the VPN, the certificates for the HTTPs need to be put in another folder with some user access.
Unfortunately i don’t remember where those are …
I used Claude Code to find an answer to my question. For anyone with the same problem the process involves:
- Generate self-signed CA private key and certificate (ensure you use extensions as indicated by csr of project webapp)
- Generate a pem file from the above
- copy pem file to /etc/lightpd/ on the device
- Restart the webserver on the device with command /etc/init.d/lighttpd restar
