It seems you copied the wrong files and now Apache is complaining about it:
AH02565: Certificate and private key localhost:443:0 from /opt/bitnami/apache2/conf/server.crt and /opt/bitnami/apache2/conf/server.key do not match
Do you still have a copy of the certificates at comodo? If so, please copy them at the expected locations instead of editing them. If not, this is the guide to generate new dummy certificate to solve the issues. Afterwards, you can create new let's encrypt certificates by following this other guide.
