Hi @aditya_k2 and welcome in the MongoDB Community!

MongoDB 4.0 reached end of life in April 2022 so my first advice would be to upgrade without waiting.

See the supported platform for Centos:

Install MongoDB Community Edition on Red Hat or CentOS — MongoDB Manual

And the MongoDB version policy:

MongoDB Legacy Support Policy

From what I see on the MongoDB Download website:

Looks like Centos 9 isn’t supported for such an old version.

Cheers,
Maxime.
