Can not access samba file share
I like using WireShark to do a packet capture. Wireshark can highlight the SMB traffic and allow you to see if the packets are flowing well. You can also analyze the SMB transactions. This is helpful because you can compare a Windows client and a macOS client to the same appliance with the same tool on the same network and see what the difference is.

You probably are negotiating the connection differently or may need the server logs to analyze what's happening not the client logs.
