Wanted to get rid of the annoying not secure https session so found these instructions.
Used zerossl.com for the 90d certificate. So every 90d I have to install the updated cert.
- CSR -> zerossl
- Generates cert and ca-bundle (as .crt files)
- Download and save on local computer, extract zip
- Copy cert into server.crt on ER4 and append key file (cat <keyfile> >> server.crt)
- Copy ca-bundle into ca-bundle.crt on ER4
That should work for updates.
