Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
The output from Certbot is warning that your configuration uses the Apache RewriteRule directive to rewrite URLs on your site, in a way that might conflict with Certbot's attempts to use RewriteRule to forward HTTP to HTTPS. Since Certbot tried to do this but it isn't working, it probably does conflict.
Here is the documentation for this part of Apache:
Hopefully whoever created the pre-existing RewriteRule can understand the interaction between this and Certbot's added RewriteRule and find a correct way to combine them so they behave as desired.
If you're not sure how to proceed, you should post your Apache configuration here (use ``` before and after the pasted configuration so that the forum displays it as code) and someone familiar with this may be able to advise you.
