Unable to connect to an SMB Share on a Mac OS Big Sur

After upgrading to Big Suf, i am not able to connect to my company's shared drive. It used to work by connecting to smb server...sorry I am not a tech person but what i used to do is to go to Finder -> cmd+K -> smb:\\(the server name). It used to work but not now after upgrading to Big Suf. Any way i can fix that? thanks.
