You are experiencing the bug described in this topic and on the servers page.
After having prevented people from using Apache for RS servers for the better part of a decade, it was finally fixed and released in version 2.4.49.
(After it had been fixed, there seems to have been no release manager for over a year. But now they’re releasing new versions again in shorter intervals, so the latest stable version is 2.4.52.)
P.S.: I took the liberty of changing the topic title, so it’s more accurate and easier to find for others running into it.
