Nginx Proxy Manager Version 2.11.3

To Reproduce Steps to reproduce the behavior:

1. Go to SSL Certificates tab.
2. Add SSL Certificate.
3. Let's Encrypt.
4. Pick domain name, enter all other valid data.
5. Click Save.
6. Get error.

Expected behavior No error

Operating System Debian 12.7 x86_64

Additional context Up-to-date docker

IP is not blocked for sure/not in spam lists/etc. I can issue a cert for reg.ru with certbot/use reg.ru in browser/use API. Don't know why NPM keeps telling me that access is denied. I suspect some internal issue or invalid exception description.

REG.RU demands about whitelisting IP for API usage are also met.
