These are the logs that are printed last on ES, but whenever I try to reach host-ip:9290 or 9390 i get failed to connect via curl command, if i try to use rest client in java i get an exception with 503 service unavailable any idea why this is happening?

It looks like you have SearchGuard installed, which is not supported here. You therefore probably need to reach out to the SearchGuard community.
