I ran into an error when trying to renew an external SSL certificate on our CloudGen Firewall.
Renewing the certificate itself seems to work fine but updating the private key throws an error: error:0906D06C: PEM routines: PEM_read_bio:no start line.
I found a port by Gavin Chappel titled "Renewing or upgrading an SSL certificate" which seemed promising but appears to be outdated.
If there are other gotcha's in the renewal process using the Firewall Admin tool please update the documentation and/or post an update to that post.
E.g. does the private key need to be changed to a different format?
The documentation refers to an "External-Signed Private key", what does "signed" mean in this context?
Thanks in advance.
