Hello there,
Can you share the exact error message or Event ID you are getting?
The connection may fail because of any of the following reasons:
Failure to connect to a domain controller to obtain a DFSN namespace referral
Failure to connect to a DFSN server
Failure of the DFSN server to provide a folder referral
To resolve this problem, you must evaluate network connectivity, name resolution, and DFSN service configuration.
Hope this resolves your Query !!
