Getting error using the SSH remote capture interface with key only authentication.

Error by extcap pipe: * (sshdump.exe:2128): WARNING *: Error creating connection: Can't find a valid authentication. Disconnecting

Tuning off key only authentication on the remote system and using password works. The private key works in WinSCP.

Assuming this is done on Windows, with an unknown target. Are there any protections on the private key (eg. passphrase?). Is a key agent being used?

Yes Wireshark on Windows. Target is FreeBSD 11.1. Have tried with both protected and unprotected private key. No, a key agent is not being used. Note, the same private key (both protected and unprotected) works in WinSCP.

Have you tried connecting via putty or another windows client with full logging turned on? My idea is, that the path might not be provided correctly, and therefore the id file either does not get loaded at all, or is the wrong one selected.
