DNS problem: query timed out looking up A for domain-name

Help
1

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. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: www.mobionizer.com

I ran this command: certbot renew

It produced this output:
DNS problem: query timed out looking up A for
www.mobionizer.com; DNS problem: query timed out looking up AAAA
for www.mobionizer.com

My web server is (include version):
XAMPP for Linux 7.2.31-1
The operating system my web server runs on is (include version):
centos 7
My hosting provider, if applicable, is:

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

I'm using a control panel to manage my site (no, or provide the name and version of the control panel):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): certbot 1.11.0

I think the problem is probably that ns2.banglaphone.net.bd (IP address 180.210.130.3) doesn't respond to DNS queries over TCP.

This is a misconfiguration by the operators of that server.

Since your domain depends on that nameserver, it is causes issues for the issuance of your certificate.

Your choices include:

  • Contact banglaphone, ask them to fix that nameserver, and wait for them to action it.
  • Change your domain to use nameservers that are working properly (Cloudflare is a good free one, but there are many choices).

This is what I presently see with nslookup

$ nslookup
> set q=ns
> mobionizer.com
Server:         127.0.0.1
Address:        127.0.0.1#53

Non-authoritative answer:
mobionizer.com  nameserver = ns1.banglaphone.net.bd.
mobionizer.com  nameserver = ns2.banglaphone.net.bd.

Hello.

This is the current status, no errors. But we are still unable to complete the cert process.

We have run this below command:
"certbot certonly --standalone -d www.mobionizer.com"

Still getting following issue:

IMPORTANT NOTES:

Mmm. I think your network (Bangla Phone) is blocking Let's Encrypt's IPs entirely.

For evidence, I tried pointing one of my domains at your web server's IP address, and it still produces a connection timeout, so the problem is not DNS related at all.

Since your nameservers are hosted on the same network as your web server, I think it's likely that both timeouts can be explained by a firewall block or other similar networking issue.
