LibreOffice uses Universal Content Providers to access files via various protocols. Due to accidents of history, LibreOffice contained 2 different UCPs for WebDav and HTTP, one based on neon and the other on Apache Serf, each with different bugs and bugfixes.

For LibreOffice 7.3, thanks to a tender from The Document Foundation, we have replaced both of them with a new UCP based on libcurl, which is designed to meet all currently known requirements, and is able to use the operating system's TLS stack on Windows and macOS.
