If you are on a work network, or any network behind a firewall, you may need to speak with your IT department or network administrator. When you do, please give them the websites below to whitelist, and the ports to open.
The minimum requirement is that TCP port 443 is open. Some firewall/proxy rules only allow for SSL traffic over port 443. You will need to make sure that non-web traffic can also pass over this port.
In addition to the minimum requirements being met, we also recommend that UDP port 3478 is open.
For the best possible experience, we recommend that UDP ports 1025 - 65535 be open.
Please let us know if you have any questions, and we're happy to help!
