Azure WebJob timeout configuration settings
You need to set SCM_COMMAND_IDLE_TIMEOUT from the portal to your desired timeout value in seconds. For example, set it to 3600 for a one hour timeout.
Go to your website's config section, find the app settings section, and add the setting.
Login to Microsoft Azure portal
Go to App Services,
Select your website
Go to settings --> Application settings tab
Create a key “WEBJOBS_IDLE_TIMEOUT” under App settings section
Save
As this is the first stack overflow error that comes up when searching for the timeout problem i want to update it from my perspective;
If expecting a CONTINUOUS webjob, this isn't something that happens by default (Even though the webjob appears to run by the rules until timeout). This is something that has to be selected in the Visual Studio Publish properties as detailed here:
https://docs.microsoft.com/en-us/azure/app-service/webjobs-dotnet-deploy-vs
Once continuous is selected and the webjob is published, this error goes away
