HI All,

We have 2 web servers , 2 app  in our prod environment. Suddenly after server reboot activity, on one of the server we are facing issue "Error registering the viewer with service". When request hit to one of the server then only user see error. We are using File Storage for the implementation. I suspect some settings or configurations might have changed in one server. What all things can we check for this ? Trace log show below error in affected server:
"Make sure you are using CacheStorage inside single-instance application deployment only."

Hi Praj,

I noticed that you have opened a support ticket for the same issue. We have replied there in detail regarding the specific environment. Here I will post our recommendation for the benefit of our community.

The config files of the two REST Service instances are identical. Unfortunately, they both use File storage, which is not suitable for web farms. My advice is to change the Storage to IStorage implementation suitable for deploying both on single instance application hosting and in Web Farms.
