When I activate http3 for the domain, I randomly get stalled requests in edge/chrome. This makes the website freeze. The origin is a NextJS app with incremental static regeneration.

Activate http3
Are you still encountering this? Does it only happen with Chrome or all browsers?
Yes!
It really is weird. We have many apps/sites that use the same technology and it’s the only domain where we have problems.
I’ve seen multiple other users who had similar problems, but they never found out why. For example https://community.cloudflare.com/t/cloudflare-proxy-suddenly-breaks-our-site/622218
We tried to check everything at the origin, but since it works really well with http2, I wonder how it could be between Cloudflare and the origin.
The topic you have linked to is mine.
We’ve had that issue twice, been through the entire debug precedure with CF support. We never got to the bottom of it, then it resolved itself. Frustrating.
We had the problem with Chrome and Edge. Didn’t check with other browsers.
