NOTES:
cert-manager has been deployed successfully!

In order to begin issuing certificates, you will need to set up a ClusterIssuer
or Issuer resource (for example, by creating a 'letsencrypt-staging' issuer).

More information on the different types of issuers and how to configure them
can be found in our documentation:

https://docs.cert-manager.io/en/latest/reference/issuers.html

For information on how to configure cert-manager to automatically provision
Certificates for Ingress resources, take a look at the `ingress-shim`
documentation:

https://docs.cert-manager.io/en/latest/reference/ingress-shim.html

<p>in ingress you are using issuer as <code>letsencrypt-staging</code> change it to production and also change <code>tls-secrets</code> it will work</p>

<p>Production url for let's encrypt issuer : <a href="https://acme-v02.api.letsencrypt.org/directory" rel="nofollow noreferrer">https://acme-v02.api.letsencrypt.org/directory</a></p>

<p>in the issuer you have used the staging url of let's encypt staging server change it to production URL and again try to get tls.cert and key it will run with https://</p>

<p>staging certificate some time not work with https and browser give error it is for testing purpose.</p>

<p>cert-manager and nginx ingress and other things are looking perfect as it should have to be. </p>
