Check if IP is blocked (


my IP

@Meriem-BM My best guess is that Let's Encrypt servers are not blocking requests from your IP.

I say this because I cannot contact that IP from my own test server. So, it is not receiving inbound requests. That looks like a general comms problem from your system and not unique to specific blocks. I only see port 22 open to that IP

nmap -Pn
22/tcp open  ssh

Can you explain why you think your IP is blocked? What exactly is the error message? Blocks are rare. Comms config problems are far more likely.

Please fill out the fields below 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. |, so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command:

I can login to a root shell on my machine (yes or no, or I don't know):

Also I find no Domain Name that maps to
Let’s Encrypt offers Domain Validation (DV) certificates which implies a Domain Name.

This really is the question. @Meriem-BM, it's exceedingly rare for Let's Encrypt to block an IP address or block, so it's therefore highly unlikely that's the cause of whatever problem you're experiencing. But if you'll let us know, in detail, just what problem you are experiencing, we can likely help you.
