I am trying to connect a websocket over the devtunnel but the connection is not fully established.
I am trying using the wss:// protocol over the https:// endpoint.

Are websockets currently supported?

    Yes websockets are supported.
    Can you share more information to help us resolve your issue?

    I am running a simple java websocket server locally on port 8080.
    My websocket client is postman for testing purposes.

    I can connect to ws://localhost:8080 with no issues.
    Also I am able to use ngrok for this port but I want to switch to using devtunnels.

    For devtunnels I use: wss://TUNNELID-8080.use.devtunnels.ms.
    This tunnel has port 8080 set to auto.

    Should I explicitly add the wss protocol for port 8080?

    When trying to connect over devtunnels, I get the callback for connectionEstablished in my ws server but nothing after that.
    No message can be received. Also no callback for closing the ws.
    The connection never moves past Connecting in the postman client.

    What am I missing?
    What other details should I provide to help debug this issue?

    Here is my verbose output:

    Is the tunnel (or the specific port 8080) set to public?

    Issue got solved without any changes on my end. Also no devtunnels update.

    Maybe a network issue solved a reboot.
