I've requested help from upstream on curl-library: https://curl.se/mail/lib-2024-05/0020.html
It looks like the regression is partially back on the 8.7.1 as well: > HTTP/2 200 > expires: Fri, 01 Jan 1980 00:00:00 GMT > pragma: no-cache > cache-control: no-cache, max-age=0, must-revalidate > x-content-type-options: nosniff > x-frame-options: sameorigin > referrer-policy: no-referrer > x-xss-protection: 1 > permissions-policy: interest-cohort=() > strict-transport-security: max-age=15552000 > vary: Accept-Encoding > x-clacks-overhead: GNU Terry Pratchett > content-type: text/plain > date: Sat, 11 May 2024 19:33:28 GMT > server: Apache > > curl: (92) HTTP/2 stream 1 was not closed cleanly: PROTOCOL_ERROR (err 1) I get both the payload and the error.
