Unable to log in to Microsoft or GitHub Account in mainland China

[guoidou]

When using the Microsoft account synchronization function, there is a problem with the login, and the data synchronization cannot be performed normally by jumping to vs code.

After the browser login is successful, the redirection fails, the information is as follows

And this

[seanbonjean]

the same problem occurred to my machine, both my Microsoft account and GitHub account have this problem

[TylerLeonhardt]

So it appears that vscode.dev is blocked in China? Does the same apply to github.dev? Can someone check for me (go to github.dev/microsoft/vscode)?

However, I can log in successfully with the Microsoft account using the old version

Yes, github.dev can't log in to Microsoft, too. This is screenshot:

[CodeZhangBorui]

github.dev isn't blocked now. But because vscode.dev is blocked, Github Web Editor unable to log in to Microsoft, too.

Same question, it doesn't work too while opening VPN and switch to other areas.

I have meet this problem on my home computer but not the company's. My home and company are on the same broadband carrier(China Telecom).

Thanks for all the info so far, I want to narrow down what works and what doesn't. Can you all give this a try?

1. Go to https://insiders.vscode.dev
2. if it does not resolve, add a screenshot to this issue with the error
3. If it resolves, Sign in to Settings Sync (the little person icon above the gear)
4. Report back if that works or not. If it does not, tell me where you get stuck
5. Go to https://vscode.dev
6. if it does not resolve, add a screenshot to this issue with the error
7. If it resolves, Sign in to Settings Sync (the little person icon above the gear)
8. Report back if that works or not. If it does not, tell me where you get stuck

If you get stuck in steps 1 through 4, please also try steps 5 through 8.

[wenda84]

i get stuck at the step 4 . Shows a phenomenon similar to the above

[TylerLeonhardt]

Thanks @wenda84, can you also start at Step 5 and see how 5-8 go?

[seanbonjean]

the insider version is working, but vscode.dev isn't

[seanbonjean]

and when I try to sign in using the insider version, the same error occurred

[wenda84]

Thanks @wenda84, can you also start at Step 5 and see have 5-8 go?

emm, i can not open https://vscode.dev/, but i can ping it. And I also tried use a proxy software, it helps me vist Github faster, but it didn't help to VSCode login.

[seanbonjean]

but I cannot ping vscode.dev

[seanbonjean]

but I cannot ping vscode.dev

sry I cannot change the PowerShell language due to windows setting limit, in English it means ping cannot find host vscode.dev

[yume-chan]

Online testing tool shows ISP DNS servers in many regions resolve vscode.dev to 127.0.0.1. Some other regions have a seemingly correct IP, but still can't establish TCP connections to it.

[wenda84]

I solved the problem by modifying the local DNS settings.
国内的兄弟们试下修改本地DNS服务器为114.114.114.114，我改了就好了。 电信自带的不知道什么垃圾DNS。

You can use Edge Addon Malus VPN to connect to Chinese Network. Remember to open Global Mode（全局模式）to let all the website use Chinese Network.

我改了DNS服务器没有解决还是一样登录不了

[GeekYang1993]

Please tell me how to solve the problem. I also encountered the same problem. Changing the DNS server to 114.114.114.114 cannot be solved

[GeekYang1993]

I have solved this problem. The operation method is as follows:

1. Modify DNS server to 114.114.114.114

2. Open CMD and enter ipconfig /flushdns to refresh DNS cache

3. Reopen vscode and log in using Microsoft or GitHub

Users in Chinese Mainland can try this method

[TylerLeonhardt]

Just to let everyone know, we are actively working on this. I can't provide too many updates as I have requested assistance from a team at Microsoft who is better suited to fix this problem, but I will ensure it is looked at and provide as many updates as I possibly can.

it does work!thank you very much!
感谢指点迷津，折腾好久了

[GeekYang1993]

The method of modifying the DNS server and refreshing the cache may not be 100% successful. I found that after successful login, the login will still fail if I log off.
通过修改DNS服务器并刷新缓存的方法不一定100%成功，我发现成功登录以后如果注销在登录也还是会失败。

+1 居然成功了

[TylerLeonhardt]

Hi all, we have done some work to get vscode.dev unblocked. Our tools say that 90% of China should be able to access the site now... Slowly increasing every day. Can you all give it a try again?

[CodeZhangBorui]

It works! I’m in Shandong, China, using China Unicom Network. Thanks a lot!

[CodeZhangBorui]

It works on China Educational Network (be used in Chinese Schools), too. And it has Chinese translation now!

[TylerLeonhardt]

I believe we have "fixed" the problem at this point. It may take a little bit more time in some locations as this new policy propagates across China but I don't believe there's any more action on our part on the VS Code team so I'm going to close this as fixed.

Let us know if you're still having this issue and if you are, what your internet provider is and what region of China you are in.
