In our environment with Apache 2.4.37-56 for EL8, some passenger applications did not work in OOD 3.1.9, so we downgraded to OOD 3.1.7. Please see following tickets.
That is unfortunate news. No I’m not sure why that doesn’t work for you. We (OSC) also run Apache 2.4.37-56 in our environment so I’m not sure why it wouldn’t work for you.
The patches we made in 3.1.9 and above were to support higher apache versions. Obviously this did not go as well as I would have liked.
It’s clear that the updates we broke your system, I’m just not sure how because I can’t replicate. That said, I’ll redouble my efforts to look into this and see if there’s something we can do for all systems.
