I have a number of users that are experiencing connection errors when starting a vision project, but not all users. The error is SocketException: Connection reset. Software Version: **8.1.20 (b2022082313)**. I am unable to replicate the issue on my devices. The log file seems to indicate the issue is due to slow download speeds, is there a way to adjust these settings? Startup log file is below: Starting Bootstrap Loader v3.0 Connect Step [attempt 1] connecting to: [http://10.212.211.12:8088](http://10.212.211.12:8088)...

Hi [Peter\_Frick](https://forum.inductiveautomation.com/u/Peter_Frick), I would suggest creating a ticket for this with the Support Department. They would be better suited to handle this issue. ---

Those kinds of connection reset problems can also occur with aggressive anti-virus software and external firewalls.
