Jagex recently released new official servers in Japan, Singapore, and South Africa on June 3rd. Currently, the Mudfish OSRS item doesn’t recognize these new routes.
It has been over a month since they launched, Please add the new Asian and African server IP ranges to the OSRS game item, just like you did for the Brazil servers recently.
As a workaround if you can’t find the game server you’re playing, you should use one of the methods at Unsupported Games.
And if you want to see it officially at Mudfish, please send me some game packets using Packet Capture with Mudfish link while playing the game with Full VPN mode.
I need some game packets to register for a new game server.
