I have 3 branches setup with MX64 devices. All internet traffic is coming back to my Main office to get filtered by an appliance. I also have 2 branches not using the MX64 and are being filtered correctly and blocking/allowing the correct sites to be accessed by my Barracuda Web Filter. The sites using the MX64 are blocking https:\\ sites when they should be allowed. For example, we use https:\\www.linkedin.com for business purposes. It is not being blocked on our Web Filter at the main office. The devices using the MX64 are coming back and stating:
Can’t connect securely to this page
This might be because the site uses outdated or unsafe TLS security settings. If this keeps happening, try contacting the website’s owner
