Talend Open Studio 7.2.1 Stucked on startup

[Anonymous]

Hello, OpenStudio 7.2.1 (TOS_DI-win-x86_64.exe) during startup remains stucked for about 20 minutes. The problem happens in all Win10-Desktop-PC of our Company, but we have no problems using ours Win10-PC at home.  I've done some traces with Wireshark , comparing the startup phase between Company PC and Home PC, and I've found that the issue happens when Open Studio try to connect to localhost websocket GET /websocket/v1/bus, during the Loading SDK components step. As you can see in the photo the last connection in Company-PC is to /api/v1/environment, instead it should be exists also a connection to /websocket/v1/bus. So the client wait 20 minutes of timeout before to go to next steps.

This is the extract from log file:

So, how we could fix the issue or is it possible to lower the timeout period?

Thanks

Hello, we've solved the problems. There was a compatibility issue with Forefront Firewall, that prevented Talend to do websocket connections. We need to remove the Forefront client, because switching it off doesn't give any result.
