Failed to update data source credentials: Timeout expired. The timeout period elapsed prior to [..]

[BBrak]

hi all, I've published a Power BI report based on an OData query to Power BI Service but I'm getting an error trying to get OData source credentials validated. The full error is: 

"Failed to update data source credentials: Timeout expired. The timeout period elapsed prior to completion of the operation."

The OData query parameters are as follows:
OData.Feed("url", null, [Implementation="2.0",Timeout=#duration(0, 0, 10, 0)])

The thing to note here is that the OData query in question only has about 700 records and 15 columns but takes quite a while to load, probably around 3-5 minutes. Another OData query that is much faster but otherwise has exactly the same connection configuration properties does not experience this problem and the credentials are updated in Power BI Service within seconds

Hence, my questions:

1) What exactly is "the timeout period" referenced in the error? It appears the duration of this timeout can't be altered by the user and is different from the timeout duration that can be entered as an additional parameter in the OData.Feed, correct?

2) What workaround options would be suggested here?

Thanks, Bastiaan

UPDATE: it turns out that ticking the 'Skip test connection' option prevents the time-out error to occur. The credentials can still be saved and were then accepted during a Refresh.
