Hi, Hoping someone can help me understand this error with my scheduled refresh. I'm seeing this error maybe once in every 7 refreshes and the table is different each time.
I have an on premises gateway. Connection to the database is fine, Query caching is on.

you can specify your own execution timeout in the SQL connector, but this sounds more like a hard limit on the SQL server side. Can you make your query run faster? Indexes, statistics etc.
