tilt: Windows10 - Error port-forwarding web (30080 -> 8080): Unable to listen on port 30080

Expected Behavior

Port forwarding should work smoothly in windows machines

Current Behavior

• Getting the following error when we updated tilt to v0.29 on windows 10 machines. This doesn’t happen on our Mac’s:

Reconnecting... Error port-forwarding...(30080 -> 8080): Unable to listen on port 30080: Listeners failed to create with the following errors: [unable to create listener: Error listen tcp6 [::1]:30080: bind: Only one usage of each socket address (protocol/network address/port) is normally permitted.]

• Potentially related to this ticket 🤔

Steps to Reproduce

• upgraded to tilt v0.29
• updated k8s_resources in tiltfile to allow it to handle port forwarding (k8s_resource(workload=‘web’, port_forwards=[‘30080:8080’], labels=‘Front-end’)

About Your Use Case

• Our frontend service starts failing to connect to BE and throws network errors; would like to have no failures when using our web service and no issues with port forwarding when on a windows machine
• Are there any extra setup steps for windows users to get this sorted out?
