It's a FAQ: https://curl.se/docs/faq.html#My_HTTP_POST_or_PUT_requests_are > When the MTU is larger, the TLS packet sequence continues This seems unlikely to me to be a curl issue. It sounds more likely to be something lower in the networking stack that's interfering. Try using Wireshark to sniff the traffic to see if the short application data packets are getting through, and if they are, if they're being acked.
