Credentials for Data Sources is not stored

[Alex_Tonkov]

Hi, 

I'm using Virtual network gateway to get an access to the PostgreSQL service in Azure to obtain data required to the report. I've created a data source for PostgreSQL and was able successfuly see the data during the creation of a data flow in preview mode. But then DataFlow couldn't refresh the data, and raise an error:

Error: <ccon>Data source credentials are missing or invalid. Please update the credentials for PostgreSQL in dataflows settings page and try again. [Path: ].</ccon> Request ID: 2be00419-135c-3844-9abb-90ac6dde2f5b Activity ID: b985d934-1f06-476f-a65f-d7dacb3ce98c

After the editing the dataflow and entering credentials again, I'm able again to see data in preview mode, but data refresh continues to fail. 

Can you please advice how to fix this behaviour?

Is this issue still occuring?

This is has just started happening with a dataflow backed by a Pro Account. We have implmented this for other clients this is the first time we have seen this isssue.

I have a similar Problem. But it only occures in some periods and ouers during the day. It is better in the afternoon/evening. I can not store the dataflow, even when I am able to see the table data in the dataflow during editing. The report runs normally without problems automatically during the night.
Strange behaviour.
