OK. Thank You.

It worked only one time yesterday, when I directly connect the PC to the camera's Wi-Fi hotspot!
When I add the camera via network cameras it seems to work stably.

Thank You

It works when I directly connect the PC to the camera's Wi-Fi hotspot.
I thought it works too when the camera an the PC are connected to the home wifi, like EOS Utility too.

If that is the only option -> Thanks a lot

For example when focus brecketing is activated in the cam. The camera take all the entire number of images that I have specified.

When Helicon Remote or Helicon Remote mobile connect to my Canon EOS R6 Mark II, the camera take automatically a picture. When the bracketing function is active, the camera take the pucture series. Is this normal?

I can't connect my Canon EOS R6 Mark II with Helicon Remote on my Desktop PC. System is Win 11. At the firewall, the connection is allowed.
EOS Utility, Helicon Remote mobile, Helicon Remote with cable connection, works fine.
Any ideas?
