From my experience, this relates to IPv4 vs IPv6.
127.0.0.1 is explicitly V4. While localhost can be V6.

while the output= wasn't accepted (it said it wasn't valid there),
Does the file exist? If not, can stunnel create it? Can you read it with an editor. Can you write into it interactively?
changing 127.0.0.1 to localhost seems to have fixed it!
What does "nslookup localhost" report?
