I have resolved the issue and I have contacted the game Accelerator support staff to have them work on both mapleroyals and the update server 185.125.230.117
Finally I found a handy Accelerator to avoid that update issue.TY for advise, but I think this issue should be investigated since we cannot connect royals in a normal way
If you are using a game booster or accelerator, I assumed you are from mainland China? You would have to contact the game boost/accelerator customer service for assistance as we are unable to confirm which network would block Royals You may request them to allow connection to "185.125.230.117 cdn.royals.ms" as per this post https://royals.ms/forum/threads/no-such-host-temporary-solution.226217/
