How to report problem with 504 Gateway timeouts when attempting DTL operations in Azure Portal?

Question

Since 2022/12/30 approximately 3am Central US time, I am getting errors from the Azure portal (portal.azure.com) on various DTL operations - listing VMs, creating a new lab). Region is Central US. I am still getting those same errors 7+ hours later.

The problem doesn't seem to happen in East US - the other region I spot checked.

There is nothing reported about about DevTest Labs on Azure status page.

Example error output from azure portal:

{
"shellProps": {
"sessionId": "14b9dab98f8349f58e0e8c15a0b8b5dc",
"extName": "Microsoft_Azure_DevTestLab",
"contentName": "DevtestLabBladev2"
},
"error": {
"message": "The gateway did not receive a response from 'Microsoft.DevTestLab' within the specified time period. (Code: GatewayTimeout)",
"code": 504,
"error": {
"message": "FetchDataError: data set Lab:DataCache:51:8",
"name": "FetchDataError",
"stack": "FetchDataError: FetchDataError: data set Lab:DataCache:51:8\n at r.t (https://portal.azure.com/Content/Dynamic/-mPDykxZ7mlI.js:73:895)\n at r (https://portal.azure.com/Content/Dynamic/fK4AzoLEiM2h.js:18:248)\n at new r (https://portal.azure.com/Content/Dynamic/fK4AzoLEiM2h.js:18:469)\n at yt (https://portal.azure.com/Content/Dynamic/fK4AzoLEiM2h.js:99:817)\n at https://portal.azure.com/Content/Dynamic/fK4AzoLEiM2h.js:99:6772",
"extension": "Microsoft_Azure_DevTestLab",
"type": "MsPortalFx.Errors.FetchDataError",
"baseTypes": [

"MsPortalFx.Errors.Error"
],
"errorLevel": 2,
"timestamp": 1508624.700000003,
"innerErrors": [],
"dataSetName": "Lab:DataCache:51:8"
}
}
}

This appears to be a basic azure infrastructure problem; trying basic lab operations in azure portal UI should not cause 504 gateway timeouts.

There does not appear to be a formal way to report an azure problem to Microsoft without having a paid support contract. But I don't need a paid support contract; I need Azure to work properly. This is an internal Microsoft problem.

Note: doing basic lab creation in East US appears to work. The gateway timeout problem may be specific to Central US. Since the most basic lab creation attempt I try, or indeed, any portal operation against DTLs in central US all give the gw 504 timeout, I am curious what the azure status page is actually checking, as it reports DTL in central US is green..

Sharing the answer for awareness.

There was an update on the ARM side which caused this product issue. The Product team mitigated the issue and users shouldn't be seeing these errors now.
If anyone is still seeing this error, let me know in the comments.

Thanks.
