Connecting to League Garena server vietnam?

Hey I can only connect to Vietnam server via the Viettal node and any other won’t work. Viettal node sometimes has huge ping spikes for me. The Routing Path shows to connect via Singapore and the ping is also good from there. But the problem is client won’t open when I connect through Singapore. I don’t exactly know how to use Advanced mode. Any help is appreciated. Thank you.

Umm… Not sure that Advanced Mode link or Multi Path Mode link are helpful for you but please check when you get a chance.
