Personal business website blocked by AT&T gateway or network. How do I get it unblocked? Support didn't help.

My personal business website is blocked at the AT&T gateway or network level. Has anyone experienced an issue where AT&T gateway or network blocked a website?  Did anyone find a solution?  I can get to my website if I use another network/hotspot, but it is blocked at a wireless and wired level.  Very strange.  Looking forward to anyone else's experience.  Would like to know how this happened and how to avoid it in the future.  Thx.

Please get back to us so we can work on getting a resolution @SteveM01.

Hi, thanks for the reply, Bryan.

My website is www.knowledgeactionsuccess.com.

I did contact my WebHost and I have confirmation that the site is up and running.

I tested the ATT network from multiple devices (Mac and PC and phone) and if I am connected to the ATT network it times out both wired and wireless.  If I use my phones hotspot/cellular network then I can hit my site and it works, but it has taken me a while to figure this out.  I am curious why it would be blocked and would like to be able to avoid this in the future.  Thanks for your assistance.

Thank you for those details! Is your Internet service established under a business account or residential?

Hi @SteveMo1, we are happy to help.

 

 

It is never the intention of the AT&T Postmaster staff to block legitimate mail. Unfortunately, legitimate messages are sometimes blocked as a result of our antispam and antivirus measures.

 

This information is intended for ISPs, email providers, customers, and other service providers who want information about the AT&T email service, how it works, and how to resolve related issues.

 

Let us know it this helps.

Thanks. I’ll try it. Also, it is a residential account for now.

Your site is working fine for me (on ATT).  I ran the following checks:

1) Load www.knowledgeactionsuccess.com in Firefox.  No issues.

2) Perform nslookup from terminal, received reply 199.250.197.3, goes back to inmotion hosting, so appears to be correct.

3) I use a third party router and use Cloudfare DNS.  To confirm that it works with the normal setup, I connected directly to the GW (bypassing my setup) and was able to load the site and had the same DNS response when sending the query to the RG which uses ATT DNS servers.

4) Ran traceroute to your website.  No issues.

 

Can you do the following so we can figure out what is going on?

In a command prompt, run "nslookup www.knowledgeactionsuccess.com." and report the response.  Here is mine for reference:

~$ nslookup www.knowledgeactionsuccess.com.
Server:		127.0.0.53
Address:	127.0.0.53#53

Non-authoritative answer:
www.knowledgeactionsuccess.com	canonical name = knowledgeactionsuccess.com.
Name:	knowledgeactionsuccess.com
Address: 199.250.197.3

If that doesn't work, then we have a DNS issue to resolve (excuse the pun).

The next step is to ping your website "ping www.knowledgeactionsuccess.com."

~$ ping -c 4 www.knowledgeactionsuccess.com.
PING knowledgeactionsuccess.com (199.250.197.3) 56(84) bytes of data.
64 bytes from ecbiz250.inmotionhosting.com (199.250.197.3): icmp_seq=1 ttl=52 time=41.0 ms

64 bytes from ecbiz250.inmotionhosting.com (199.250.197.3): icmp_seq=4 ttl=52 time=41.9 ms

4 packets transmitted, 4 received, 0% packet loss, time 3005ms
rtt min/avg/max/mdev = 40.978/41.686/42.168/0.443 ms

If the DNS is working and the ping is working, you should be able to load the site.  If DNS is good and ping is not, then it may be a routing issue that is out of your control. You can run a traceroute to the server. Windows command is tracert.  I'm using linux which is traceroute.  The -I specifies to use ICMP which is the default on windows.  Windows command is "tracert www.knowledgeactionsuccess.com."

~$ traceroute -I www.knowledgeactionsuccess.com.

Thanks for the help.  After a month or more of troubleshooting my blocked website, it was resolved by my web hosting company unblocking my public IP address (starting with 76.###.###.###).  I can now access my site again.  Took for ever to figure that out.  I hope this helps others who have this problem.
