Please advise...

I am experiencing an authentication error when running an remote SQL backup job with local file system destination.

Error returned...
Cannot open backup device '\\VHOST\BA_SQL_10_7\BPSERVER_^_BPSINSTANCE-BPSSamples-20180827.195801.847-FULL.bak'. Operating system error 1326(The user name or password is incorrect.).

the BA user identity is set to the local administrator and performs File System backups to local containers and external drives no problem.
the SQL connection credentials have full access to the database. We can see the database contents and can select them no problem.
