Failure to Load Character IDs

When running the Convai plugin on a machine that is missing certain popular root certificates you will receive errors when trying to fetch characters' data and you will usually see this error in the chat widget Load Failed for Character ID: <Character ID>.

To fix the issue, you need to disable SSL verification from Unreal Engine, this can be done by going to Edit menu, select Project Settings and search for Verify Peer and disable it.

Disable Verify Peer

Another solution is to install any browser like Google Chrome or Fire Fox which usually install the required certificates automatically.
