trouble accessing samba shares in Dolphin

I am getting a timeout error when trying to access a samba share via Dolphin. Accessing it via the command line works, but only if I use the -m SMB2 or SMB3 options. For example:

smbclient // -m SMB3 

works, but

smbclient // 

returns the error:

protocol negotiation failed: NT_STATUS_CONNECTION_RESET

So, I apparently have to specify the protocol level via the command line to get this to work, but I’d really like to be able to use the graphical interface of Dolphin as well. Any ideas on how to fix this would be much appreciated. Thanks.

Add the following to the [global] section of /etc/samba/smb.conf

client min protocol = SMB2
client max protocol = SMB3
