forwardPorts in devcontainer.json not taking effect

I’ve got the following forwardports in my devcontainer.json:

"forwardPorts": [5900, 5901, 6080],

Yet when I launch the codespace, the codespaces extension doesn’t think any are forwarded:


Thanks for reporting this! We had a regression in the UI, that prevents these configured ports from sometimes showing up. We’ll have a fix out for that early this week :+1: In the meantime, if you spin up a server from the terminal, and cmd/ctrl+click it’s URL, that should still work. Additionally, if you need to retrieve a URL for a specific port, you can run “npx codespaces-port ” to grab it.

Otherwise, we’ll update this topic as soon as the UI is fixed next week. Stay tuned!
