I am using Umbraco 8.4 version and my website is running on the azure app service. I have cloned the existing website and database and published it on another azure app service. When I open the website, I am getting the below error.
Boot failed: Umbraco cannot run. See Umbraco's log file for more details.
-> Umbraco.Core.Exceptions.BootFailedException: Boot failed.

I have checked all the configs files of Umbraco but was not able to troubleshoot the error.
Thanks Imran Khan
According to your logs, your problem looks like a caching issue and your v8 umbraco website can't get the data from NuCache.
Regenerating the cache data might solve your problem.
I don't know much about NuCache but here is the Umbraco documentation for caching and here is a blog post about NuCache and how to explore it.
