Technical issue regarding lobby connectivity and Loss Forgiveness

I would like to report a technical issue regarding lobby connectivity and Loss Forgiveness,
My friend is currently using a VPN (Cloudflare WARP) and is unable to successfully join our lobby. Although he is in Silver rank and I am in Gold—meaning he can solo queue—he is failing to connect to our actual match. Because he is failing to load in, our team is receiving 'Loss Forgiveness,' and we are not losing any Rank Points (RP) despite the match outcome. I wanted to report this behavior as it seems to be an exploit or a technical bug caused by the VPN connection. I believe this is occurring due to the game's DDoS protection measures
