Hi All,
I am posting this information believing that it would certainly save someones time. We are using Sql Server Reporting Services 2008 R2, the objective is to generate the reports bu connection to Sql Server Services 2008 R2. We observed the below error while trying to use 'Test Connection' in Report Builder.
'Unable to connect to the data source. Please verify the connection properties and credentials.'
'The connection either timed out or was lost.'
We exactly don't know the reason for the issue, but we have accidentally figured out a solution for this issue. (a permutation and combination approach)
used fully qualified domain name for the SSAS server name in one environment and used strictly server name(without FQDN) in another environment.
Both of them were working differently in the two cases, but were working fine. However the issue was resolved with no error.
Best Regards, Paramesh.
