HTTP3 / QUIC Incompatibility?

Hello, on both Firefox and Chrome (and Edge), when I am connected to OpenVPN, I cannot watch videos (e.g., youtube) or load certain websites (e.g., quora) unless I disable HTTP3/QUIC support in the browser. This happens on both my computer and my Android phone. Any app that does not allow me to disable HTTP3/QUIC downloads very slowly. My openvpn server is setup on UDP Port 443. Does that have something to do with this problem? as I understand QUIC also uses UDP 443. I can't be the only one with this issue? I've searched far and wide and couldn't come across a mention of this on the interweb.
