Hello Esa,
Here are some steps you can take to troubleshoot and address the problem:
1- Check the cookie affinity (session affinity) configuration on your Azure Application Gateway. Ensure that it is correctly set up to maintain user sessions across multiple requests.
2- Check the logs of the Azure Application Gateway for any relevant information or errors.
3- Ensure that the path and domain settings of the cookies generated by your backend match the settings expected by the Application Gateway.
4- Use Azure PowerShell to enable detailed diagnostics on your Application Gateway.
Set-AzApplicationGatewayDiagnostic -Name <ApplicationGatewayName> -ResourceGroupName <ResourceGroupName> -Enabled $true -Categories 'All'
