Edgerouter 4 and https SSL certs


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.

Quick instructions:

  1. CSR -> zerossl
  2. Generates cert and ca-bundle (as .crt files)
  3. Download and save on local computer, extract zip
  4. Copy cert into server.crt on ER4 and append key file (cat <keyfile> >> server.crt)
  5. Copy ca-bundle into ca-bundle.crt on ER4

That should work for updates.
