So I am trying to setup proxy for CentOS8 and keep getting errors when it tries to proxy the AppStream. The error that normally is there is “failed to synchronize cache” but when i turn on verbose it says it cannot find the modules.yaml.gz file. Is there a configuration to fix this it seems like its just not proxying this file?

This looks to be a known issue with Nexus, [NEXUS-21311](https://issues.sonatype.org/browse/NEXUS-21311)
