SSL WebVPN "Failed to validate server certificate" - cannot access https sites
I've setup a WebVPN to access the configuration interface of IP phones (Aastra) from outside the LAN. The WebVPN is working fine as long as the IP phones accept http connections, but if I enable https only (required for security reasons), I can't connect. WebVPN says:
Certificate Error - Failed to validate server certificate
when trying to connect to the phones.
I've googled a lot, but there seem to be no configuration options to accept all certificates without validation? Is there any way to import the certificate of the Aastra IP phones?
