500 - The request timed out error in Sitecore. The web server failed to respond within the specified time

-

After Login on Sitecore CMS does not redirect to Content Editor and throws error 500 - The request timed out. The web server failed to respond within the specified time error.

I have deployed our Application on PROD CM and CD instance on the Azure PAAS and the instance is working fine. When I try to log in to the CM instance, I can log in, but instead of redirecting me to the Sitecore Content Editor it's throwing me an error 500 - The request timed out. The web server failed to respond within the specified time.

After logging into the CM site, the following error is displayed: 500 - The request timed out. The web server failed to respond within the specified time

After login into the CM instance:

500-request-time-out-1

500-request-time-out-2

I have verified the AllowedCorsOrigins and Redirect URL in the identity

server and CM instance in both Sitecore.IdentityServer.Host.xml and Sitecore.Owin.Authentication.IdentityServer.config respective files and all are correct.

The same code and deployment work perfectly with the Pre-PROD environment on the Azure PAAS.

Solutions:

After analyzing data from a period of time where there was an issue with slow /identity/externallogincallback requests.

Based on the Availability and performance section in the Azure portal, I see slow requests to /identity/externallogincallback gone after a few days (approx 7 days):

500-request-time-out-3

Also, I see 3 5xx errors during this period, most likely these errors are related to /identity/externallogincallback request timeout:

500-request-time-out-4

After that verified the Master DB DTU and it was returning 100% spikes all time so I increased it to 50 DTU. To verify the DTU spikes, go to the database resource under the resource group on the Azure portal and select Metrics options under Monitoring in the left panel. To calculate the price you can use Azure Pricing Calculator.

500-request-time-out-5

Hope it helps to analyze the issue if someone faced the same.

Happy Sitecoreing ðŸ˜Š

While upgradation to Sitecore 10.2, I was to restore the database on the Managed Cloud Service Azure SQL Server. I have connected the Azure SQL server on my local SSMS and started to import the Database using the option Import Data-tier Application. While importing the database using the above option you need a BACPAC file instead of a .bak file. So I was to create a BACPAC file of the database from my local. Go to the database, right-click and select the Export Data-tier Application option under the Task menu. After clicking on the next, while creating the BACPAC file you may get the below error: Solution: Go to the Users in that Database.
