My system is Win10 with WSL2, I ran a gogs docker container (from ubuntu in WSL):

    83b2a8833235   gogs/gogs                    "/app/gogs/docker/st…"   17 minutes ago   Up 17 minutes>22/tcp, :::10022->22/tcp,>3000/tcp, :::10080->3000/tcp       gogs

I found that I can cURL it, but cannot use browser to visit it:

    >curl -vvv http://localhost:10080
    * Rebuilt URL to: http://localhost:10080/
    *   Trying ::1...
    * TCP_NODELAY set
    * Connected to localhost (::1) port 10080 (#0)
    > GET / HTTP/1.1
    > Host: localhost:10080
    > User-Agent: curl/7.55.1
    > Accept: */*

    <a href="/install">Found</a>.
    * Connection #0 to host localhost left intact

Using netstat -a -o I can see the address in Active Connections:

TCP          xxxxxxx:0          LISTENING       13152

But I cannot visit using browser: Cannot Visit Using Browser

Anyone has any hints?

    Do you have a proxy in your browser ? Or anti-virus which blocks ? The proxy may block of you use the "unsafe port" 10080...

  • @vidarlo it is WSL2, sorry for the confusion

  • @Dom did not see any strange things on the proxy (only the "Automatically detect settings" is set to ON)

    The error text is misleading: Chrome isn't having trouble connecting, Chrome isn't trying to connect -- see superuser.com/questions/188058/… . Firefox gives a much better error: "This address is restricted / This address uses a network port which is normally used for purposes other than Web browsing. Firefox has canceled the request for your protection." Your best solution is to choose a different port. Jul 28 at 23:34
  • Thanks @dave_thompson_085 for the knowledge, it works when I change the port.

Most Browsers restrict 10080 for security reasons on localhost


  • Change the Port.


Google Chrome blocks port 10080 to stop Nat slip streaming attacks
Chrome Platform

Additonal Informations:

Currently, Google Chrome is blocking also FTP, HTTP, and HTTPS access on ports 69, 137, 161, 554, 1719, 1720, 1723, 5060, 5061, and 6566.

  • As Also, the most modern browsers do the same.
