When we access our website from our internal network I get "There is a problem with this website’s security certificate." message.
When I access it from outside, I don't have that issue at all. When I view the certificate, it is Parallell, which I believe it is the platform web developer used, but other than that, I don't have any idea how to fix this. This started as soon as we hired a new web developer, and they wanted to host the web pages on their servers. Because this does not happen outside of our network, they will not help us.
