UPDATE! (No server problem)
I found the solution, i just turn off the power saving mode on my phone and the servers suddenly appears. Thank you for all the helps and suggestions. I appreciate it. I can finally play :")
Dont know if this is a bug? Or the game isnt playable in my country, i have stable internet connection, i keep on refreshing. I tried using Vpn. Still no server appears. TIA for further answer.
