Is there an existing issue for this?

Current Behavior

I’m getting two new issues using the latest prerelease version and they are somewhat related so I’m going to put them both on here. They both seem to occur right after the other

First: Cannot access a disposed object.
Object name: 'SslStream'.

@OlegRa Also as a side note, I looked through the user wiki and tutorials and didn’t see an example for newer users to utilize the throttle parameters so just thought it would be useful to add an example

@OlegRa I’m able to replicate this by disabling the ethernet adapter and then enabling it again. Socket stays closed and doesn’t attempt to reconnect. However when running the same code without messing with the ethernet adapter, I can see that it does attempt to reconnect on its own.

@ooples How does socket reconnection logic (most probably your mean one of the streaming clients) relate to the HTTP timeout? If you have a problem related to streaming client’s reconnection in the latest SDK release, please, report it as a separate issue.
