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 uses several different video backends. To check which video backend your space is using, enter your space and open the debug overlay with ctrl-shift-d or cmd-shift-d. On the left side of the screen, look for the value of the ‘A/V Backend’ field.

Since the backend can occasionally change depending on service availability, you may want to unblock all backends to ensure connectivity.

If your backend is Gather, you need:

Service

Host

Ports

Explanation

Gather router

router.gather.town

443 TCP

The router is used for signaling on the Gather video backend.

Twilio

See Twilio's Knowledgebase for hosts in your region

443 TCP (TURN TLS)
3478 TCP, UDP (TURN)
5349 TCP (TURN TLS)


Note that you do not need to allow traffic on UDP ports 10000-60000, we only need the three mentioned ports.

We use Twilio to accommodate firewalls and restrictive networks. Instructions for unblocking their IP addresses in your region are available on Twilio's Knowledgebase

 

If your backend is Livekit, you need:

Service

Host

Ports

Explanation

LiveKit

gather.livekit.cloud

443 TCP

This endpoint is used for signaling on the Livekit video backend.

Twilio

See Twilio's Knowledgebase for hosts in your region

443 TCP (TURN TLS)
3478 TCP, UDP (TURN)
5349 TCP (TURN TLS)


Note that you do not need to allow traffic on UDP ports 10000-60000, we only need the three mentioned ports.

We use Twilio to transfer media when behind a firewall or restrictive network. Instructions for unblocking their IP addresses in your region are available on Twilio's Knowledge base
