@trobr, is the Ubuntu 16.04 machine you're connecting to behind a firewall and/or does it require a proxy to access the internet?

If so, can you please check the value of $HTTP_PROXY from VSCode's integrated terminal?

If you are not behind a firewall/proxy, could you please try running this on the remote to see if it can reach the IntelliCode service?

$ curl https://prod.intellicode.vsengsaas.visualstudio.com/api/v1/model/common/python/intellisense-members/output/latest

Our service should respond with a JSON object similar to the following:

ubuntu@ubuntu:~$ curl https://prod.intellicode.vsengsaas.visualstudio.com/api/v1/model/common/python/intellisense-members/output/latest

Thanks!My remote machine is behind a proxy,But whether I turn the proxy on or off, I get the same result.When I run this code in my remote machine:

curl https://prod.intellicode.vsengsaas.visualstudio.com/api/v1/model/common/python/intellisense-members/output/latest

I got this result:

{"model":{"id":"88630A1B4C077752096ECAA576B92C7D3FA1","friendlyName":"Base (Python)","language":"python","analyzer":"intellisense-members"},"output":{"id":"BC98A65409D042A99DDAF47DC30E1530","modelId":"88630A1B4C077752096ECAA576B92C7D3FA1","targetedInputIds":[],"version":1556898645147,"status":"OutputReady","trainingResults":{"displayClasses":[]},"blob":{"schema":"azureBlobStorage","name":"Output_88630A1B4C077752096ECAA576B92C7D3FA1_BC98A65409D042A99DDAF47DC30E1530","azureBlobStorage":{"readSasToken":"https://cdsmprodstg.blob.core.windows.net/models-prod-output/Output_88630A1B4C077752096ECAA576B92C7D3FA1_BC98A65409D042A99DDAF47DC30E1530?sv=2018-03-28&sr=b&sig=UfAUL6QnjdySf7S5T8X5ezAnucrETvjH7bpWj%2BCybzA%3D&se=2019-05-08T03%3A27%3A02Z&sp=r"}},"created":"2019-05-03T15:50:45.1474524Z","updated":"2019-05-03T15:50:45.6375847Z"}}(pytorch)

This issue seems to be caused by the fact that the IntelliCode service can not download automatically in remote machine.

It seems that proxy settings are forwarded from local VSCode to the remote: microsoft/vscode-remote-release#213. I was able to reproduce this by setting the http.proxy setting locally and connecting to a remote, after which the IntelliCode extension could no longer reach the service.

You should be able to work around this by adding your proxy config to the remote settings. That will override any proxy settings that are being sent from local VSCode.

{
    "http.proxy": "http://127.0.0.1:8123"
}

Let me know if that works for you.

You are right! It‘s useful for me.

Thanks!

Great, I'm glad that worked for you. I updated the title to make it easier for others to find if they have the same issue.

it seems you use remote-ssh, in remote-wsl it seems a bit different. If proxy service is in windows, use 127.0.0.1 in remote setting will be helpless, see #165 (comment)
