Failed to renew certificate

Help
43

We know you got port 80 (HTTP) to work because you got a cert.

But, did you have to do any routing to get port 80 requests to that Apache? Like port forwarding in a router for example?

If so, have you checked that port 443 is routed to port 443 on that Apache?

I just reached out to the network administrator and port 443 is accurately routed but different error now the site is taking too long to load

# This site can’t be reached

**lms.nphcda.gov.ng** took too long to respond.

Try:

* Checking the connection
* [Checking the proxy and the firewall](chrome-error://chromewebdata/#buttons)
* [Running Windows Network Diagnostics](javascript:diagnoseErrors())

ERR_CONNECTION_TIMED_OUT

This does not look like anything to do with your cert.

Can that network admin help you find out why HTTPS requests are not reaching your Apache?

HTTP requests are still reaching an Apache 2.4.41 (Ubuntu)

Can you show us the result of this

curl -4 https://ifconfig.io

105.112.253.58

That's not the IP that is in the public DNS which is:

lms.nphcda.gov.ng.	0	IN	A	105.112.249.244

See

You should also have your network or admin people look at these DNS issues

Can port 443 reach your server?

49

yes was able to reach it

I cannot reach your site using HTTPS (port 443). I can with HTTP (port 80).

The "filtered" status usually means blocked by a firewall. I think you need to ask your network admin to explain why this is shown

curl -I https://lms.nphcda.gov.ng
curl: (7) Failed to connect to lms.nphcda.gov.ng port 443 after 247 ms: No route to host
