So, it is failing very early during the negproto request: SMB2 302 Negotiate Protocol Request SMB2 143 Negotiate Protocol Response, Error: STATUS_INVALID_PARAMETER which seems related to these commits in v5.18.8 16d5d9100927 smb3: use netname when available on secondary channels ca83f50b43a0 smb3: fix empty netname context on secondary channels Have you tried reverting both in v5.18.8 to see if it works? I built v5.18.8 but couldn't reproduce it against w22 server, though.
