Default self-signed server certificate

Currently running 3.2 P8, just a query on Default self-signed server certificate.

Mine have 90 days till expire, but says not is use, do they still need to be renewed? I don't have a renew option on System Certificates page, only generate self signed.

@craiglebutt if its not in use then you can you don't need to renew, you can delete unused certificates to cleanup.

You can edit the self-signed certificate and renew it for 10 years. That allows you to keep it around in case you need it in the future and mostly not have to worry about it. 🙂
