Deploying to Azure App Services causes timeout (Error Code 504)

Franck Desbrosses 51

Hi,

I'm deploying an app on a linux container in App Service, and I keep getting "Error: The gateway did not receive a response from 'Microsoft.Web' within the specified time period. (CODE: 504)" when updating settings (even with the Azure App Service Settings task).
I also get an error via the portal when I try to manually update the settings, it saves but I get an error (with no detail however).

What can I do ?

Apologies you're experiencing this issue.

Kindly change/add the application settings value to WEBSITE_ENABLE_SYNC_UPDATE_SITE = false and then check.

I have seen similar error using regional VNet. If you’re using a regional VNet and there is another Web App in the same App Service Plan which is integrated with a subnet. Try using a different one.

See this doc: https://learn.microsoft.com/azure/app-service/web-sites-integrate-with-vnet#regional-vnet-integration
“You can have only one regional VNet Integration per App Service plan. Multiple apps in the same App Service plan can use the same VNet."

Hi , we are also facing the same issue, when trying to deploy we are getting Timeout issue: In our case we are having 6 app services under single appservice plan, and all are integrated to the same VNET. what is meant by "Try using a different one"? should i integrate different appservices with different vnet?

how exactly you update app settings? We use Az module for that and didn't have such issues:

$app = Get-AzWebApp -Name $appServiceName -ResourceGroupName $resourceGroupName  
  
$appSettingsCurrent = $app.SiteConfig.AppSettings  
$appSettingsNew = @{}  
foreach ($kvp in $appSettingsCurrent) {  
	$appSettingsNew[$kvp.Name] = $kvp.Value  
}  
  
$appSettingsNew["foo"] = "bar"  
  
Set-AzWebApp -Name $appServiceName -ResourceGroupName $resourceGroupName -AppSettings $appSettingsNew

Through a pipeline task, here's the yaml :

steps:

task: AzureAppServiceSettings@1
displayName: 'Azure App Service Settings: xxx'
inputs:
azureSubscription: 'xxx'
appName: 'xxx'
resourceGroupName: 'xxx'
appSettings: |
[
{
"name": "XXX__YYY__ZZZ",
"value": "myVal",
"slotSetting": "false"
},
...
]
connectionStrings: |
[
{
"name": "MyName",
"value": "My connection string",
"type": "Custom",
"slotSetting": false
},
...
]

Hi, I am running the following command to deploy app service

I am using following az cli version
azure-cli 2.26.1 *

az webapp deploy --timeout 900000 --clean true $(deploy_trace_level) \ --resource-group $(azureResourceGroup) \ --name $(azureAppName) $(slot) \ --type zip --src-path \ $(System.DefaultWorkingDirectory)/$(app_archive) 2> /dev/null
I did add WEBSITE_ENABLE_SYNC_UPDATE_SITE = false

but after 4min51 seconds my command times out.

attaching the debug log

`
