Can you please share the entire contents of the remote tunnel access log? Also, do you have any proxies configured on your device?

this is the entire contents of the remote tunnel access log，and i don‘t have any proxies configured.

[connor4312]

This looks like it may be some service issue @derekbekoe

[derekbekoe]

Looks like there may be a proxy preventing the connection from succeeding.

Please verify that the domains listed in this document are accessible and do not generate SSL/TLS errors on your machine:

You seem to have some network configuration or issue that prevents you from connecting to the tunnel service.

I have changed several computers and have re-installed the latest version of vscode, but it is always the same problem

[trry-hub]

Is there a solution? Ask the boss for advice

I've tried these domains and they're all working

[derekbekoe]

The "Dev Tunnels" domains also need to be accessible from the machine.

You will want to allow *.rel.tunnels.api.visualstudio.com

Me too.
I followed the suggestions regarding network connections mentioned above, and after referring to this document: https://learn.microsoft.com/zh-cn/azure/developer/dev-tunnels/get-started?tabs=windows, I can confirm that I can access Dev Tunnels. However, I still cannot connect to the remote tunnel.

[liudonghua123]

I have the similar problems when open github codespaces since yesterday approximately.

[derekbekoe]

@liudonghua123 please check the response headers. It's likely there's a proxy that's causing that request to fail.

[liudonghua123]

I can confirm I am not using proxy. And I also checked the response header from the devtools. But it's empty.

[derekbekoe]

@liudonghua123 for Codespaces, it may be best to review the items at https://github.com/community/community/discussions/categories/codespaces or post a new item there.

[adamlynn36]

@xinxing277 I have encountered the same problem, according to the meaning of the log: error sending request for url (https://asse.rel.tunnels.api.visualstudio.com/tunnels/silent-cat-40lp3tl?tokenScopes=host&api-version=2023-09-27-preview)
It is because the URL cannot be accessed. After trying to use the global proxy, the tunnel resumed normal use

After trying to use the global proxy, the tunnel resumed normal use

The output of my window is like this

When I open the requested linkhttps://asse.rel.tunnels.api.visualstudio.com/tunnels/silent-cat-40lp3tl?includePorts=true&tokenScopes=host&api-version=2023-09-27-preview, it returned 404 like this.

I really can't access the url. But I haven't used a proxy. When I view the system agent on the command line, it shows no.

Excuse me, after you solve this problem, can you access such a URL? What is its correct output? I don't know how to solve it.

[liudonghua123]

I just got ERR_CONNECTION_TIMED_OUT when I try to execute GET request to the failed request.

China has blocked it，microsoft devtunnel，

you can access it by using some special means，

It was usable in the first few months
