External Storage SMB/CIFS not working after upgrading to Nextcloud 21.0.1

I was previously running nextcloud 20, now after upgrading to nextcloud 21 all of my external storage folders are broken. My environment is fully upgraded Debian 10.8 with php7.4, apache2, mariadb. As a test I also set up another Debian 10.8 server from scratch with a brand new install of nextcloud 21 and I’m getting the same error message. See below for the event log errors. I did try connecting manually to the same share via smbclient and that worked fine so I know it’s nothing to do with smbclient. TIA!
