Unable to update connection credentials.

Hi! I am unable to edit my credentials to my Dremio connection in Power BI Web Service. It throws out the following error:

Unable to update connection credentials.
Unable to connect to the data source. Either the data source is inaccessible, a connection timeout occurred, or the data source credentials are invalid. Please verify the data source configuration and contact a data source administrator to troubleshoot this issue.

Details:

Timeout expired. The timeout period elapsed prior to completion of the operation.

I am able to use the connection and credentials in Power BI Desktop but I cannot do a refresh in the Web Service.

Any idea how to resolve this? Thanks!
