Hi @richard.esmond, This looks like you might have a firewall that blocks connections from certain IP address ranges. If not, you could look in your web server logs to see if it was your web server that deliberately dropped the connection from Let’s Encrypt. ---

I am actually watching the log and the HTTP calls look like they are working fine. Can you try this link and see if you get through?

I definitely can, but if the certificate authority’s validation servers can’t, it seems like something must be blocking them. ---

Actually I see the transactions coming through. I have been assuming that there is something about how I am handlling the transaction is somehow off. ---

Are you sure that you aren’t just seeing your and my tests? If you start over with a new certificate request (that you don’t test for yourself and don’t post here), what will you see in the web server logs? ---

I watched a dozen calls to my server even before I posted this message. I am considering creating a new request. ---

> [@richard.esmond](#): > > I watched a dozen calls to my server even before I posted this message. Well, I tested it about 5-6 times and I think other random people reading this forum may have tested it about 3 times, so if you tested it about 3 times yourself, that might be enough account for the dozen hits without a successful visit from the Let's Encrypt CA itself... ---

They seem to mostly be coming from 17.133.7.117 ---

That IP address is owned by Apple, probably not Let’s Encrypt. Let’s Encrypt can reach your server, at least sometimes: [https://acme-staging-v02.api.letsencrypt.org/acme/authz/-it8z6A-yH2DoUEE-pzCIKSIIzIS1EwITamDVq4UaAg](https://acme-staging-v02.api.letsencrypt.org/acme/authz/-it8z6A-yH2DoUEE-pzCIKSIIzIS1EwITamDVq4UaAg) ---

LOL - I’m getting trolled by apple! I’ll redo the request and see if that fixes it. Thanks! ---
