Realtime Stock Data Stream

Has anything changed with the realtime stock stream? in the last few days all of a sudden I am getting 0 bars via the real time stream. Regardless of if I use a specific symbol or * when subscribing.

I am using the C# API and currently on the latest version 6.2.1 For alpaca.Markets nuget package and 6.2.0 for alpaca.markets.extention.

Nothing has changed in my code other then upgrading nuget packages. I am going to revert to an early version and try again but I was just curious if it was a known issue or not.

Regards,
Adam

It does appear that there is an issue with 6.2.1 reverting to earlier versions solved the problem.
