Ranked PvZ Heroes Error

Hi, I'm trying to play ranked multiplayer in PvZ Heroes, but I always get the message "No Match Found." I tested it on different internet connections (I'm traveling today), and they were working fine. I also played other multiplayer games like Brawl Stars and Genshin Impact without any problems.

Does anyone know what might be causing this?

I even changed my internet's IP settings to different static addresses, but it still didn't work.

Thanks for the help!
