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”!(conn,fremote_path) |> Stream.into(!(flocal_path)) |>

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


Upgraded to OTP 22 and it is fixed

Found entry that said OTP 21 had regressed unc access.
