I installed Transmission 3.00 on a Windows Server 2016 Essential.
Everything works fine except for the remote acces.
From http://localhost:9091 everything is fine, but from http://serverip:9091 I got the following error:
How can I solve this?403: Forbidden
Unauthorized IP Address.
Either disable the IP address whitelist or add your address to it.
If you're editing settings.json, see the 'rpc-whitelist' and 'rpc-whitelist-enabled' entries.
If you're still using ACLs, use a whitelist instead. See the transmission-daemon manpage for details.
