PowerBI: Unable to connect with SQL database with Sept Update - Error during Pre-login handshake

I am all of a sudden getting an error on all of my reports connected to an external db using Windows creds. to login.   This just started occuring 2 days ago and we have yet to resolve.   


Error reads: 

Microsoft SQL: A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: HTTP Provider, error: 0 - )


Any Help would be so greatly appreciated.

@Allisond, I am experiencing same issue (SQL Server connection), but only with datasets using incremental refresh... same with you?

@musicbydannyd   Yes,  our team just fixed by removing the update.  Refresh is working now.

@Allisond, ditto... removed inc. refresh and was able to republish to service. I hope MS has a fix soon!

For clarity, this issue isn't resolved - rolling back an update is a temporary workaround at best, and I'm not seeing a way to prevent automatic updates so it could happen again at any time.  This issue is affecting multiple users on multiple PC's.  I'm currently on Version: 2.85.681.0 64-bit (September 2020).

We're seeing this same error when attempting to refresh datasets in the Power BI Service via our On-Prem Data Gateway. Anyone found a workaround yet?

Same problem here with Version: 2.85.681.0 64-bit (September 2020)

connecting to sql server 2016


Manually reverting to august version can't be considered a workaround if the september update is still being pushed

@Allisond  How did you remove the update?


Do you have a saved copy of the earlier version? 


Does anyone know how to disable this annoying monthly update thing?
