500 Server Error, WP on Openshift

I’m getting a 500 Internal Server Error when I try to connect Powerpress to Blubrry Services. I’ve turned on Debugging in wp_config but I don’t see any additional info about the error.

This is hosted on Openshift. I’ve tried different versions: 5.10, 6.3.3 and 7.0.3 I also tried the powerpress getID3 plugin.

I tried deactivating all other plugins but still get a 500.

Any suggestions?
