Error certificate SSL in costum domain

First of all, congratulations on the site. I’m a newbie to next.js, but thanks to the documentation provided I’m learning. My problem is creating the ssl certificate in a custom domain. I have created the subdomain CNAMES from “_acme-challenge” to “”. I have the CAAs created with, but they give an error (Something went wrong, please try again or contact support.) when generating the certificate. Whether it is manual and I put the certificate that I created with letsencrypt, as if it is the automatically generated one.

I would appreciate my guidance on what I am doing wrong. Thanks

Hi Izu!

Thanks for good words. We have just improved our error handling, try to generate your certificate again and hopefully new error messages will help you out, if not definitely reach out to us again.

All the best,

Thanks for the solution.
