Bad routing

im having a problem. when trying to connect to League of Legends Brazil server, the routing is sub optimal. The routing is redirecting to US East (Vultr 1, 2) and then to Sao Paulo (im from Argentina). i tried many combinatios of the mudfish servers, but none of them seems to work efficiently. is there a way to fix this?
Thanks in advance.

Could you please confirm that it’s also same with Full VPN mode enabled? I’m not sure that LoL Brazil game server works fine with Mudfish at this moment because the last update was quite long ago.
