Remove Certificate

I am running a site on Ubuntu. Originally I installed Nginx as reverse proxy and installed Lets encrypt using certbot. but due to issue with Nginx I installed Apache and reissued SSL for apache .
I have disabled Nginx . however, I get SSL error time to time , and i believe due to ssl for nginx still in the system.
how can i disable this ssl or nginx ssl configuration .

Would you explain more about the error?
