• VSCode Version: 1.51.0-insider (user setup) (Commit 89c002ab02f87102d91efc83c191ef1174756c6a)
• OS Version: Windows 10 Pro ( 19041.572 )

Can confirm the same result as @ayush987goyal, when starting VSC I attempt to enable Settings Sync and I get the following log:

I have tested with the insiders version of sync, with both MS and GitHub as auth. sources.

Testing with the standard version of sync results in:

[2020-10-17 11:33:50.936] [userDataSync] [info] Using settings sync service https://vscode-sync.trafficmanager.net/

After restarting VSC and forcing login and sync once more, using standard version of sync I can get it to propagate the settings and it functions as expected.

Assigning to @lszomoru for initial investigation on 502 error from server.

Please reassign it to me if there is anything needs to be done on client side.

[lszomoru]

@ayush987goyal, @eamondo2 - apologies for the inconvenience. The errors that you have seen were caused by one of the Azure App Services getting into a bad state due to which it was unable to connect to the CosmosDB backend. We have mitigated the error by restarting the App Service and we are working with our Azure partner teams to track down the root cause, and put improvements in place to avoid this error condition in the future.

@ayush987goyal, could you please try to re-enable settings sync and let me know if you run into any issues. Thanks!

[iyashpal]

I deleted all machines from sync history and tried to sync the latest settings. Then I try to re-enable the Setting sync I got the same error (I am logged in with github):

[aaryanporwal]

I reinstalled VSCode and when trying to turn on setting sync, I got the same error (MacOS 11.0 Beta):

Here I am facing the problem.

[lszomoru]

Sorry about that. I am taking a look at the service-side telemetry now and will circle back with my findings.

[lszomoru]

It looks like one of the App Services has gotten into a bad state. I am working on mitigating the issue.

[lszomoru]

We have mitigated the issue at 2020-10-27 13:50:00 UTC. Could you please re-enable settings sync and let me know if you are still seeing any errors. I will follow up with our Azure partner teams to get to the bottom of the reason why the App Service instance has gotten into a bad state. Apologies for the inconvenience.

[aliyyousuff]

It worked. Thanks.

[aaryanporwal]

Worked for me too,
Thanks!

@lszomoru I also recently ran into this error: unfortunately it seems it is still happening on 2020-10-28:

[lszomoru]

Unfortunately last night we have had a reoccurrence of this in one of the European App Service instances. The issue has been mitigated at 2020-10-29T06:06:00Z. Can you please go ahead and re-enable settings sync and let us know if you are still seeing any errors.

This morning I have also received an update from the Azure team that they have tracked down the root cause of these network issues, and a fix for it is already checked in and will be included in the next release train. Until the fix is rolled out, we are exploring a potential workaround to avoid another reoccurrence. Apologies for the inconvenience.

[Larswa]

I am in Denmark, and are still seeing this on both my laptop and my desktop pc. Could there still be Azure outages causing this?

[lszomoru]

Sorry about that @Larswa. Yeah, it looks like another reoccurrence. Restarting the App Service now.

[Larswa]

Hey @lszomoru Thanks for the update. Will test and revert shortly.

[reznord]

Hey @lszomoru I am still getting the same error. I just tried to sync just now and it isn't syncing properly.

I am in Lisbon, Portugal.

[Larswa]

Sorry about that @Larswa. Yeah, it looks like another reoccurrence. Restarting the App Service now.

And I can confirm that its working again for me. Thanks @lszomoru !!!

Thanks @Larswa and @reznord for the confirmation. Apologies for the inconvenience.

Sorry about that @Larswa. Yeah, it looks like another reoccurrence. Restarting the App Service now.

I can confirm it works now as well. Thanks a lot
