While trying to renew certbot certificate, got an error. (Nginx, Certbot, Node.js)

This is the error:

Performing the following challenges:

During handling of the above exception, another exception occurred:

I suspect the error is about Nginx configuration, but I don’t know where exactly.

Those are my domain records:
