Hi @yash,
I think the best at that stage would be to upgrade, since you’re using v2.4 which is from 2018.
Best would be to create a new server on a Debian10 and migrate your data using this tutorial: Passbolt Help | Migrate passbolt CE from install scripts to Debian package
Otherwise you can try to follow the instructions provided in the healthcheck under [HELP] after the [FAIL].
Cheers,
