Power BI Report Builder report processing timing out

im getting the below error everytime i run a paginated report using a power bi dataset that i have access and permissions to use.

"An error occured during local repotr processing.
An error has occurred during report processing.
Query execution failed for dataset "MasterDataset".
The connection either timed out or was lost.

Response status code does not indicate success. 500 (Error in Running XMLA in Dedicated)."

Can you please help?

Does it having anything to do with "server":"pbiazure://api.powerbi.com/","database":"sobe_wowvirtualserver-******" being offline due to the below error:
