PLS file not playing in WEBRADIO

Hello, I have a question, I have created a pls file according to the some files that were already preinstalled in the WEBRADIO section on the volumio folder.

The code looks like:

[playlist] NumberOfEntries=1 File1=

When I play it on the computer it works perfectly, however when I put the file in the WEBRADIO folder, Volumio doesn’t want to play it and skips to the next file in the list.

What could be the problem?

Thank you
