Can Play but download failed with error 400 (response error)

Server Version#: 1.29.0.6244

I don’t understand why but, on my local network I can play & download video assets. But, as soon as I am outside my home network I can play but not download assets and I got an (response) error 400 … I guess that it might be related to some firewall stuff… Then, why can I still play media ? this issue is not device related (tested with many, different location, users…)

If anyone has a tip you’re more than welcome…

btw/ On my router I have open & forward the 32400 port (the one configured on PMS).

I’m having the exact same issue, please let me know if you find a fix
