eventual ip leak when using http2 with proxies?

[sla-te]

Is there a possibility, that when using http2 the real ip might leak? I am having some weird issues with a server, that I can only reach through a proxy...

You've not really given enough information here for anyone to be able to help.

You'd need to describe what you're doing, and what behaviour you're seeing, etc...

AFAIK it's possible with http3 multipath QUIC
