127.0.0.1:3080 Not Opening
Fix 127.0.0.1:3080 not opening by checking the terminal URL, keeping the local process running, or forwarding the port when DSH runs over SSH.
On this page
First, match 127.0.0.1:3080 does not open
This page targets 127.0.0.1:3080 does not open. The full message can contain a few extra words on different operating systems or Node.js versions, but the core error code or phrase should match.
127.0.0.1:3080 does not openlocalhost:3080 not openinglocalhost 3080 not working127.0.0.1 3080 not workingWhen searching or asking for help, copy the full error and remove API keys, private repository names, usernames and sensitive paths.
If DSH runs on your own computer, keep the terminal open and use the exact URL it printed. If DSH runs on a remote server, your browser's 127.0.0.1 points to your own computer, not the server; create an SSH port forward first.
What 127.0.0.1:3080 does not open means
The browser cannot reach the DSH Web UI. The local process may have stopped, the port may differ, or DSH may be running on another machine.
Common causes of 127.0.0.1:3080 does not open
- DSH exited after an earlier startup error.
- The first npx download has not finished.
- DSH started on a port other than 3080.
- DSH is running on a remote SSH server without port forwarding.
- A system or browser proxy is routing localhost incorrectly.
Source trace for 127.0.0.1:3080 does not open
These links are pinned to the 0.1.2-alpha.5 / 49a606b snapshot used for this page. They help separate 127.0.0.1:3080 does not open from failures produced by Node.js, PowerShell, the operating-system network stack or filesystem permissions.
Fix 127.0.0.1:3080 does not open
- 01
Read the terminal first
Confirm that the DSH process is still running. Use the final Web UI URL it prints, and resolve any EADDRINUSE, EACCES or package-download error before refreshing the browser.
- 02
When DSH runs on this computer
Open the exact printed URL in a browser on the same computer. If you started DSH with --port 13080, use the 13080 URL instead of 3080.
- 03
When DSH runs on a remote SSH server
Run this command on your own computer, keep the SSH session open, then visit http://127.0.0.1:3080 in your local browser.
ssh -L 3080:127.0.0.1:3080 user@server - 04
When the remote DSH port is different
Match the forwarded port to the port used by DSH. This example forwards remote port 13080 to the same local port.
ssh -L 13080:127.0.0.1:13080 user@server - 05
Check browser or system proxy bypass rules
On managed networks, make sure localhost and 127.0.0.1 are excluded in the browser or operating-system proxy settings. A process-level NO_PROXY variable does not guarantee that a desktop browser will use it.
Verify 127.0.0.1:3080 does not open is fixed
- The DSH terminal process remains active.
- A local launch opens the exact printed URL.
- For SSH, the tunnel stays connected and the forwarded local URL loads DSH.
- Do not keep refreshing the browser while the terminal shows that DSH has exited.
- Do not expose the DSH port directly to the public Internet just to avoid SSH forwarding.
- Do not assume that 127.0.0.1 on your laptop refers to a remote server.
