Some campus and corporate networks, VPNs, and firewalls will by default block traffic for Gather video calls. If you are using a campus or corporate network, VPN or firewall, and are having trouble accessing Gather, you can try the following actions to fix it:
-
Disable your VPN or Firewall
-
Visit your VPN provider's support website and try different connection options
-
Change your connection to a different server or network if your VPN will allow you to do so
-
Ask your network administrator to unblock the following endpoints, which we use to provide video calls on Gather.
Gather's server addresses have changed as of Nov. 14, 2024. Please have your network administrator update your network's firewall rules.
