Help

HI.
Apparently because newbie here, cannot pm this:

run:
#certbot certonly --standalone -d

got:

An unexpected error occurred:
requests.exceptions.SSLError: HTTPSConnectionPool(host='acme-v02.api.letsencrypt.org', port=443): Max retries exceeded with url: /directory (Caused by SSLError(SSLEOFError(8, 'EOF occurred in violation of protocol (_ssl.c:1131)')))

Apparently this has to do with my ip - address being blocked.
Can you allow this please:
185.100.87.241

We've unblocked this IP address. It was involved in DDoS attacks against Let's Encrypt some months ago, so if you've had this IP address for a long time, please investigate whether your system might be compromised.

Thanks.
This is a new server, so whatever happened then should not take place anymore.
If it does, please let me know!
