finding games in competitive

Not sure if anyone else have posted this issue before, but I am constantly having trouble finding games in the competitive playlists (I mainly play h2a arena but also some h3). although sometimes it takes seconds to find a game in competitive, most of the time it would go on for 15+ minutes without a game found. I am not sure if this is a server or population issue, or my connection, since I was able to find games in social quite fast and consistently (10 seconds for a full 4v4 game). I thought this was caused by solo queuing since I heard that the game matches parties to parties and solos to solos, but I also had problem finding games when full party queueing.
Although it is fun playing in social, I prefer ranked since I could give myself reason to improve and earn better ranking.

Things about my side: I live in west coast United States. average 25 ms to the nearest server, open NAT, usually solo queueing but sometimes 2 to 4 player party queueing. currently ranked 13 in h2a arena. usually plays in popular times about 5 to 10 PM PST.

Things I have tried when I can’t find a game (but didn’t work): back out to menu and go back in, restart the console, restart the router, switch internet connection

any help would be very appreciated. happy holidays.
