Can't find games ranked/casual (PC)

Bought the game yesterday for PC and have not been able to join a single ranked/casual game, battle lounge is working fine.

Its just stuck in “Waiting for your opponent”.

I have opened up the ports mentioned here

Also tried disabling all anti virus and firewall.

Any other tips to get matchmaking/ranked working?

edit: also tried bypassing the router completely but it still doesn’t work.

Disabling ipv6 seems to have solved the issue.
