2019 Windows server is not allowed to access Terastation Shared folder

[BuffaloHelp]

Hello All,
     We have a TS3410R. It has plenty of available storage.
We recently noticed one of the new servers wasn't configured to do it's backups on the NAS. When we tried to access the NAS shared directory using the windows backup software we get the following error:
"The Specified path is not a remote shared folder"

We've checked several of the other servers and some have SMB 1.0 installed and enabled and some do not. The 1 server I am specifically talking about does not have it installed. I'd rather not install SMB 1.0 on it. I also checked the NAS and it has SMB auto enabled. Leading me to believe that I should in fact be able to access the NAS from the 1 server in question to set up the backups.

Any helpful suggestions are most welcome.
Thanks.
