Fix Port 3080 Already in Use for DeepSeek Harness
The Web profile defaults to port 3080 and accepts --port as an app argument. Confirm which process owns the port, stop only a process you recognize or select another unused port; never use a broad kill command copied from an unknown page. This page separates verified behavior from community reports and marks the release-candidate context so you can act without mistaking an observation for a permanent guarantee.

dsh web --port 3081What is verified now
The Web profile defaults to port 3080 and accepts --port as an app argument. Confirm which process owns the port, stop only a process you recognize or select another unused port; never use a broad kill command copied from an unknown page.
Evidence basis: Official --port behavior + locally test before publish. The status was checked on 14 August 2026; re-check the linked source after any dsh release.
Safe workflow
Use the smallest reversible workflow first. Do not add community plugins or paste credentials while validating the base behavior.
- Copy the exact error and record OS, Node and dsh versions.
- Apply the narrow checks on this page in order.
- Verify with a minimal profile and escalate with sanitized logs if it persists.
Verify before moving on
A successful result should be observable: a version string, reachable local URL, valid provider response, loaded configuration, or disappearance of the exact error. If the result differs, stop and capture sanitized evidence rather than stacking unrelated fixes.
- Record the exact dsh, Node or Python version.
- State the operating system and installation method.
- Link the first-party source and include only sanitized logs.
First-party sources
Open the original source before acting on a changed version or unresolved community report.
