We were tying to change the certificate on our web portal for anywhereUSB +, but looks like we removed it and can no longer connect into our device via https (we get connection refused) is there a way to change the certificate configuration from the SHH commandline or a way to import our certificate from SSH?
As far as your question about changing the CERT config via SSH, the following link has information on how to install your own signed SSL certificate:

If you want to erase the current configuration and start over, hitting the Reset switch twice will wipe the configuration and re-generate the self-signed certificate. Just remember that this will also wipe your password, so you’ll need the password from your device label to login as admin.
