A specific web application that uses large 99.5KB .CSS files is causing a net::ERR_INCOMPLETE_CHUNKED_ENCODING when being accessed from a computer on a high latency network (across the Atlantic ocean). We are not able to replicate the problem from any closer devices, but multiple computers (and phones) using multiple separate internet connections across the Atlantic exhibit the same issue.
We ran into similar issues with H2 and H1 over SSL, though it was net::ERR_CONNECTION_RESET errors instead. We eventually replicated the issue on H1 with SSL off to minimize the variables. If we bypass HAProxy and use TCP port forwarding directly to the backend web server, the issue no longer occurs. So it seems to be related to HAProxy being in the mix, though I don't see any errors in the logs. Packet captures from both ends and config files are available for download here: https://drive.google.com/file/d/1nrHdsdpXyMi5uAGAQ7HZBSZd-x0pYVQP/view?usp=sharing We are using HAProxy 2.7.7 on Ubuntu 22.04. Any ideas what may be causing this issue? Thanks!
