When you try to activate Interview Mode, you may see this message:
"Could not start the interview session. Please contact support if the problem continues. A network issue occurred."
The most common reason for this message is that malware is present on your Mac, and is running a local proxy which is interfering with Ecamm Live. The malware must be removed before it will work.
We recommend running a scanning tool like Malwarebytes or similar to remove any malware and then trying Interview Mode again.
If this does not help, you should contact support for help.
Also, if you are on a heavily restricted office network, your IT administrator may have to open certain ports or whitelist certain servers. Please see this guide for network administrators.
