dsh plugin hub blank while the CLI still works

When a dsh plugin hub page is blank but the CLI still lists packages, the install and the backend are probably fine. The page and the command line read different resources, so one can fail while the other keeps working. A useful diagnosis follows the layer that produces the blank, not the layer that produces the list.

Reading the dsh plugin hub blank as a layer problem

A blank page is a renderer symptom, so the useful question is what the renderer received, not whether the backend can answer.

The CLI talks to the installed package and the local profile. It can confirm that the Hub package exists, that the profile is readable and that a version is registered. None of that proves that the browser or desktop client downloaded the files needed to draw the market.

The page needs a shell, a script bundle, styles and at least one data response. If any of those pieces is missing, the panel can stay empty while the surrounding interface still looks normal. A single failed asset is enough to produce a large blank area.

The scope of the blank is the first useful observation. A blank market panel with working navigation points at the Hub bundle, while a completely white window points at the client or the network. Write down which one you see before touching any setting.

That note also protects you from changing several things at once. If you clear a cache, switch browsers and reinstall in the same minute, you lose the ability to tell which action mattered. The observation is cheap and the attribution is valuable.

Checking the client before blaming DeepSeek Harness

The client decides what it can render, so an older client can fail on fields that a newer Hub entry depends on.

Start with the client version and the release notes for that version. A blank panel that appears right after a client update usually involves a rendering change rather than a missing package. The notes often mention the Hub or a new field type.

Extensions and hardened browser profiles are the next suspect. A content blocker can remove a script that the page treats as required. Try a clean profile before you touch the installation, because that test costs almost nothing.

Another browser or another machine separates a local rendering problem from an account or network problem. If the same account renders the Hub elsewhere, the package is probably healthy. If every client shows the same blank, the version line deserves a closer look.

Reinstalling is tempting and usually unhelpful at this stage. It removes the installed state that you might need to inspect, and it rarely fixes a missing asset in the browser. Keep the install intact until the evidence points at it.

Following the assets a dsh plugin hub page loads

Data can arrive while the panel stays empty, and that combination points at assets rather than at the index.

Open the page with the browser console visible and reload it once. Failed script and style requests appear there with their paths and status codes. A cluster of 404s is more informative than the blank itself.

Then read the network panel for the Hub data request. If the request returns a body while the panel remains empty, the data layer works and the renderer does not. If the request fails, the blank belongs to the backend or the route.

1. Open the page with the developer console visible.
2. Reload once and note every failed script or style request.
3. Check whether the Hub data request returns a response body.
4. Record the status code and content type of that response.
5. Compare the failing asset paths with the installed Hub version.
6. Restart the client so packaged assets are reloaded.
7. Repeat the check in a clean browser profile.

The comparison in step five is the one people skip. Asset paths change between releases, and a stale path tells you that the client and the package disagree. That is a version question disguised as a network error.

Hard refresh and a client restart are reasonable after you have recorded the failures. Clearing every cache first is not, because it can erase the evidence and make the next failure look random. Record first, then clear.

Comparing versions in the DSH plugin stack

The Hub and the core release on separate schedules, so a recent Hub can legitimately expect a core that you have not installed yet.

Read the Hub version from the installed list or the market entry. Read the core version from the CLI version command, and keep both numbers in the same note. Two lines that look unrelated are normal, but they still have a compatibility range.

A blank page immediately after an upgrade is the classic mismatch symptom. The Hub may be rendering a field that the older core does not send, or the core may send a shape that the older Hub does not understand. Either direction produces a panel with nothing useful in it.

Check the DSH Plugin Hub entry and the repository for a compatibility statement before changing anything. If the statement names a minimum core version, compare it with what you actually run. If there is no statement, treat the combination as untested rather than assumed safe.

Rolling back is a last resort, not a diagnosis. It can restore the page while hiding the reason, and the next upgrade repeats the problem. Align the versions in the documented order and keep the old release available in case the new one misbehaves.

Using the CLI to shrink a DeepSeek Harness problem

The CLI is a good witness for installation and a poor witness for rendering, so use it to eliminate layers rather than to explain the blank.

Run the plugin list command and confirm that the Hub, the DeepSeek Harness plugin behind the market, appears with a version. This rules out a failed install, a wrong profile and a package that was removed. It also gives you the exact version to compare later.

Inspect the active profile next. Users sometimes install into one root and open a client that reads another, which produces a plugin that exists but never loads. The CLI can show which profile it used, and that path is worth writing down.

A direct API request can show whether the data endpoint answers at all. Treat a successful response as evidence for the backend and a failure as evidence against it. Do not treat either result as proof about the visual layer.

What the CLI cannot do is see the browser cache, the blocked script or the stale asset path. Those live in the client, and no amount of command-line confirmation will clear them. Use the CLI to eliminate the backend, then return to the renderer.

What a blank dsh plugin hub leaves behind

The blank is a boundary marker: everything on one side answered, and everything on the other side did not.

If the CLI answered and the data request returned content, the remaining problem is in the assets or the client. Reinstall the Hub or update the client only after that evidence is on the page. A clean install can fix a broken bundle, but it should be a response to a finding rather than a ritual.

If the data request failed, the Hub package may be installed while its route is not. That is a backend or profile question, and reinstalling the browser will not help. Follow the request path and the profile before changing the client.

If the whole interface is white, the client or the network is the better suspect. A proxy that rewrites or blocks the shell can produce a blank window that has nothing to do with DSH plugins. Test a direct connection before editing proxy rules.

Record the finding in one sentence: which layer answered and which layer stayed silent. That sentence is the real result of the diagnosis, and it makes the next occurrence much shorter. Keep it with the version pair so the next reader does not have to repeat the checks.
