Hello Support,

I keep being disconnected from Sierra charts my Error is code 10053: An established connection was aborted by the software in your host machine.
The documentation online provides a limited explanation what exactly is the issue.

Can i send the message log for analysis? Maybe there is a deeper issue. This has been happening since last week, before that I had no problems.
