the steam servers working on mobile

Hi I need help creating match making functionality with my game, I don’t know which service to use for hosting the server and implementing further functionalities, I’ve tried AWS and photon still no luck. Can anyone help me out what to do?
I’ve used steam for the PC version but not able to find a solution for my android project.
Does steam support android as well?
Also what is the best way out for this problem?
