Interesting. Working on reproducing and not hitting the same issue. Are you using the latest Firefox build (83.0)? And are you doing any special javascript blocking?

[AaronCrawfis]

Good catch, I'll get this updated. Thanks!

[dybxin]

The version of Firefox I use is 82.0.3. and i not run any javascript blocking.

Can't reproduce, can you try another browser and re-open if issue persists?

[dybxin]

ok, the problem still exists, Currently, the problem caused i can not get some docs content. if provide some other way help me read markdown? I have tried several browsers, also colleagues have the same problem.

[AaronCrawfis]

@dybxin reopening.

Interesting, I'll help get to the bottom of this.

When you open the dev console (right click, inspect element, console) are there any errors being thrown?

Also are you able to join our discord server (https://aka.ms/dapr-discord) and message me there? I can hop on a chat to diagnose in real time.

[dybxin]

@AaronCrawfis thanks a lot. following is errors the console output.

[AaronCrawfis]

@dybxin what happens when you visit http://code.jquery.com/jquery-3.5.1.min.js directly on your browser?

[dybxin]

@AaronCrawfis i visit http://code.jquery.com/jquery-3.5.1.min.js directly, the result is refused to connect.

ping code.jquery.com

tracert code.jquery.com

[dybxin]

Turns to be an issue with the VPN of the user. As a workaround one can clone repo, find and replace: http://code.jquery.com/jquery-3.5.1.min.js to https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js

and then serve docs locally

[nesherhh]

I can confirm the issue. I'm from germany. Not using any VPN. Visiting direct - http://code.jquery.com/jquery-3.5.1.min.js gives me after hitting F5 about 10 times I get the content of the file. But after some idle time hitting F5 gives me again ERR_CONNECTION_RESET

[sanderobdeijn]

I have the same issue without a vpn in the Netherlands. I have no problem loading https://code.jquery.com/jquery-3.5.1.min.js directly. But I do get an ERR_CONNECTION_CLOSED on the URL in the dapr doc page.

A workaround I found is open the dev console and pressing F5 until you get a load without errors and then the navigation works for me.

It seems to be a flaky bug.

Germany and China are same. They both have big LAN instead of real Internet. I don't think this issue can be reproduced by someone who have real Internet.

@dybxin I've confirmed that this website is accessible in China https://www.boce.com/http/code.jquery.com.

And I can download this file without VPN on my browser. Please double check with your telecommunication provider. I'm using China-telecom network in Shanghai.

Another possible case is that GFW is randomly throwing network package for this website. If that's the case, there is nothing we can do.
