Letsencrypt SSL not trusted by firefox & chrome?

I have tried to generate SSL via letsencrypt via terminal. It generates successfully. I take the privkey and cert and put it manually on the website through cyberpanel. restart LSWS. Open up firefox and firefox says it’s not secure. If I view details on the certificate, it is the correct chain and key.

What’s going on here?

Turns out I had messed up some configuration. Was able to hire an expert to fix it.
