User get the above error while running the report.
Cause: Crystal Reports Cache server is disabled for some reason.
Resolution: Enable the Crystal Reports Cache server
Crystal Reports Cache Server:
Intercepts report requests sent from clients to the page server. If the cache server cannot fulfill the request with a cached report page, it passes the request on to the Crystal Reports Processing server, which runs the report and returns the results. The cache server then caches the report page for potential future use.
