Depending on the way VPN is set up, many users may end up using the same IP, and this might result in rate limiting. What it means is that the API could think it’s getting spammed by so many requests from a certain IP, thus blocking connections.
If there are issues connecting to a certain network, turning off the VPN can be a good starting point. Oftentimes, this solves the issue completely.
