[HELP] Using Dash in an offline environment

[chaisaijuice]

Hello :)

im using Domino Analytics Distribution Py3.6 R.3.4 in an offline Environment behind a corporate Firewall.

This are my installed dash-components:

dash                     1.3.1
dash-core-components     1.2.1
dash-daq                 0.2.1
dash-html-components     1.0.1
dash-renderer            1.1.0
dash-table               4.3.0
dash-table-experiments   0.6.0
django-plotly-dash       1.0.1
jupyter-plotly-dash      0.3.0

Describe the bug
After I publish an App nothing renders.

This is my app.py Code:

and this is the error message:

All *.js are reachable from the offline Environment with 'requests_pathname_prefix': ''

I'm not sure whats I can do now and would appreciate any help!

yeah you've clearly gotten the js files to serve, but it seems like you may need a different routes_pathname_prefix? That's odd though, as requests_pathname_prefix needs to end with routes_pathname_prefix and the former is already blank.

I suspect folks in https://community.plot.ly/c/dash will have more thoughts about what's going on if you post this there.

This is an odd symptom - something is handling the _dash-layout request but yielding a blank response? What do you see if you look at the request with _dash-layout at the end of its url in the network tab?

Hey @alexcjohnson! :)

1. routes_pathname_prefix
I tried using 'routes_pathname_prefix': '/test/', just to see what happens:

Clearly now it tries to find the *.js files in a subfolder called /test/, but the path without this prefix is correct.

It also adds it infront of the files i have in the assets Folder (red square), but I kinda hacked the Right path into it, so I dont think it has to do with requests_pathname_prefix

2. https://community.plot.ly/c/dash
I already opened a case there:

In hope chriddyp will have some time to answere :D

3. _dash-layout - Network
You had the Right guess!

There are multiple Tabs:

Headers
Request URL: https://<my.domain>/_dash-layout
Request Method: GET
Status Code: 200 OK
Remote Address: 10.131.67.145:443
Referrer Policy: no-referrer-when-downgrade

But the url "https://<my.domain>/_dash-layout" cant work, there is nothing.

But if I look the Location up where my _dash-component-suites is, there is also a Folder named _dash-layout but it uses the wrong prefix, like you said.

Preview
< Blank >

Response
< Blank >

Timing
CAUTION: request is not finished yet!

So its a timeout because it is the wrong Directory.

But the JavaScript files have the Right prefix, why not the assets and _dash-layout
