Body

None of the port forwarding is working for codespaces. Runing ReactJS and MeteorJS, tried adding ports manually and get the following error:

Unable to forward localhost:3000. Timed out performing tunnel_management_client_create_tunnel_port after 10000ms

Check Firewall Settings
Ensure that there are no firewall rules or security software that might be blocking the ports you're trying to forward.

Verify Configuration
Double-check that you're using the correct port numbers for your ReactJS and MeteorJS applications. In your case, ReactJS commonly runs on port 3000 and MeteorJS on port 3000 or 4000 by default.

Check if Ports are Already in Use
It's possible that another process is already using the ports you're trying to forward. You can use a command like netstat or lsof to check which processes are listening on those ports.

Restart Codespaces
Try restarting the Codespace. Sometimes, there may be temporary issues that can be resolved by restarting.

Use a Different Port
If the default port (in this case, 3000) is giving you trouble, you could try using a different port for your application. For example, you could try using port 3001 or 4000.

Check Codespaces Documentation
Review the Codespaces documentation and community forums for any known issues or solutions related to port forwarding with ReactJS and MeteorJS.

Review Codespaces Configuration
Make sure that your Codespaces configuration is set up correctly. You might have missed a step or there could be an issue with your specific configuration.

Update Codespaces
If you're not using the latest version of Codespaces, consider updating to the latest version. Newer versions may have bug fixes or improvements related to port forwarding.

Hello @pacificnm was this resolved? I'm facing similar issue, none of port forwarding is working for codespaces, Although I'm able to work around this using ngrok

[pacificnm]

I have not resolved it however i was able to use codspace using Visual Studio Code desktop version fine so I got around it, but kinda of annoying.

[nwogu]

Actually, mine is the opposite, Visual Studio Web, works well with port forwarding, but VSCode Desktop doesn't

can you check your dns server?

[pacificnm]

Nothing wrong with DNS server or network, port forwarding works fine on another laptop on the same network. I think its something with the browser because on the same laptop that's having issue Visual Studio Code Desktop works fine. I am running same version of chrome with settings sync between the laptops, at a loss as to why one wont work.

try removing cache from Chrome

@pacificnm
I'm sorry you are experiencing this issues.
I took a look at your codespaces and it does seem that something in your browser could be causing the request to not go through.

Could you try with a couple of browsers? There could also be a VPN or local firewall blocking the request?
Could you also try maybe disabling browser extensions that could be intercepting the requests?

If this issue persists please reach out to GitHub support so that we can get more information from you like network HAR file and logs.

Unblock this domain in your firewall: tunnels.api.visualstudio.com
