On-premises data gateway intermittent connection (paginated reports only)

We have multiple paginated Power BI reports running on the service. The gateway Status goes offline and when the end user runs the report, the below error is thrown:

Maybe gateway version update could be a nice approach (you have an old version) but I think you have to check hints in your error text..."trust relationship" etc.
