I am trying to use GPAC to stream a mp4 file via DASH to an Enensys MediaCast gateway.  Here is the gpac command line:

```
gpac -graph -log-file=gpac.log -i video/playlist.m3u reframer:rt=on -o 'http://10.21.15.82:8082/uploads/161/manifest.mpd:gpac:segdur=10:cdur=1:asto=9:cmaf=cmfc:profile=live:dmode=dynamic:hmode=push:template=$RepresentationID$-$Number%03d$$init=init$'
``` 
For an unknown reason, the MediaCast gateway is not seeing the DASH init segments. Unfortunately, there isn't a lot of debugging available on the MediaCast gateway, other than a vague error message of "No DASH init segment received". The minimal documentation on the MEdiaCast gateway says it is looking for init segments with the name format of "$RepresentationID$-init.mp4", which is what gpac appears to be producing.

There are no errors in the gpac log file initially, but after a short while, the following starts appearing in the gpac log file:

```
[HTTP] Failure - body: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>403 Forbidden</title>
</head><body>
<h1>Forbidden</h1>
<p>You don't have permission to access /uploads/161/2-001.m4s
on this server.</p>
</body></html>

[HTTP] Error parsing reply for URL http://10.21.15.82:8082/uploads/161/2-init.mp4: Authentication failure (code 403)
[HTTPOut] Failed to close output /uploads/161/2-001.m4s: Authentication failure

``` 
The error repeats with the segment number incrementing.

Any help is appreciated!
