Looks like connecting to port 445 is timing out but falling back
successfully to port 139. So what exactly is the problem? Does the program
not do what you expect? Could it be that because you have the loglevel
set high, you're getting some exceptions that are confusing you?

To prevent trying and failing to connect to port 445 (do you have a
firewall?), use :139 in your URLs [1].

Otherwise, from what you have shown me and the "session established ok"
and subsequent SMB I can't see anything actually wrong aside from the
port timeout due to being blocked.

[1] You can also set jcifs.netbios.hostname (see the 1.2.5 release notes).
