Greetings @maciej,
This is indeed odd. As you said it appears an initial connection is possible but then suddenly the connection fails. This doesn’t seem to be a known issue as far as I’m aware.
Can you reliably reproduce this issue? What happens if you remove the device from the list and re-add it does it still occur?
Could you also try the following suggestions:
- What happens if you add the device after opening/creating the project? By the way what kind of project are you working with?
- I noticed you’re using the stable release of the extension. Could you try the early access version. This version has a number of fixes that may address the issue you’re seeing.
If none of the above helps could you provide a step by step of everything you’re doing leading up to the error.
Best Regards,
Jeremias
