[FoxRefire]

Reported license servers

• Nagra(VDS7B9J3) // Closes add other providre like vodafon3 #17
• Skyshowtime // Closes could be possible to add scheme of skyshowtime ? #40
• imggaming

Background

These license servers are most likely validating the validity of the tokens or rejecting responses based on CDM client information.
If anyone is able to investigate the cause of these license server problems, please feel free to leave a comment or send a PR to this issue.
I am not willing to investigate any further issues caused by specific license servers.
