Mounting smb shares after upgrade to Catalina not working

I have a NAS storage device connected to my router on my internal network which is protected by a username & password. Prior to the upgrade to Catalina my 2016 15" Macbook Pro had no issues connecting to these shares using smb://routername/share. After the upgrade to catalina I can no longer connect to the network shares. It keeps asking me for my username & password, and no matter what I enter the dialog box keeps coming back. When I try on the command line using "mount_smbfs //username:password@routername/share mountpoint" I keep getting the error message "mount_smbfs: server rejected the connection: Authentication error". If I go into the router and remove the credentials from the shares, then the mount works fine. I know the credentials are correct (I reset them in the router).


I've also re-enabled NetBIOS as described in this article (https://medium.com/@gobinathm/how-to-access-smb-printer-shares-in-macos-catalina-10-15-17ea91d2c10b) but that did not help.

Very helpful! Thank you! I also have a couple of WDSHARESPACE NAS devices. I went into each NAS device and saw that AFP was enabled. Then I went to 'Go', from the MacOS Finder menu bar, selected 'Connect to Server', and entered in the string that you listed in your reply below. I entered the username and password, and it worked perfectly!


The link at the bottom was also a good overview of AFP, SMB, etc. that provide some simple explanation.


afp://username@<NAS ip address>/sharefoldername
