TLDR - Make sure FIPS is disabled on the host and in the container.
After much troubleshooting and research, we figured out why it wasn’t working. FIPS was enabled on our host RHEL VM that our docker container runs on. On your docs. its clearly stated that SonarQube does not support FIPS. Docker containers inherit the FIPS settings of the host. Disabling FIPS on the host solved our issues with not being able to access the Cryptographic libraries for vulnerability scans. I guess FIPS was preventing the usage of the crypto libs that were needed to decrypt the json files for the Roslyn scans.
Thank you all for your help!
