I also see something like
(09:38:09) http: Performing new request 0x55d2d6b8e620 to contacts.skype.com.
(09:38:09) http: Request 0x55d2d6b8e620 performed without success.

when trying to anyhow react to new buddy request and its still appearing on every start. Is there at least way to remove this request? In official client there is no request :(
