Let’s encrypt this domain name has reached the maximum number of authentication requests Why?

Let’s Encrypt has rate limits for many endpoints. You can read about them here: https://letsencrypt.org/docs/rate-limits/

In many cases, thre is a misconfiguration of a client/host and it is failing at some stage of the issuance process and starts spamming an endpoint until it gets rate limited.

If you need help with your client please provide the following information 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. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
