Error when closing call in webclient

[SweetAction]

When ending calls in the webclient, I get this error:

Exception of type System.InvalidOperationException occured in 'processDropCall' line 5440. Message: Invalid connection Id

Fresh install of 3CX v16u1 on Debian.
Latest Chrome on Windows 10.

Any ideas?

Hi,

Do you have a deskphone assigned to this extension?

While in the WebClient, what do you have selected here (phone or client)?
