Error streaming into a file on a fileshare

I am getting a file oor directory not found trying to stream to a file on a fileshare.
I can stream the file to a local file just fine.
Any suggestions or help is appreciated.

flocal_path = “//xxxx-users/USERS/bwxxxx/My Documents/bwwdata/bwsftpfile.xlsx”
SftpEx.stream!(conn,fremote_path) |> Stream.into(File.stream!(flocal_path)) |> Stream.run

(File.Error) could not stream “//xxxx-users/USERS/bwxxxx/My Documents/bwwdata/bwsftpfile.xlsx”: no such file or directory

Regards

Upgraded to OTP 22 and it is fixed

Found entry that said OTP 21 had regressed unc access.

Thanks
