Is AT&T Personal Hotspot blocking ports 80 and 443 for websites hosted on AWS?

Is AT&T Personal Hotspot blocking ports 80 and 443 for websites hosted on AWS? 

 

I have a website in development on AWS EC2. I am unable to access it from my laptop via a Personal Hotspot (PH) connection on either ports 80 or 443. Port 81 works, but I don't want to add a port number every time just because I'm on PH. Ports 80 and 443 work fine on AT&T wifi, and on other wifis e.g. Google/Starbucks, with no other changes. Others can hit the website when I can't. Other non-AWS-hosted websites work fine via PH.

 

If the ports are blocked, any suggested workarounds other than switching telcoms? Can you whitelist the site's AWS Elastic IP for me? I DON'T want my site's users to be unable to use it bc they are also using PH.

Hello @bretlowery!


Welcome to the Community Forums! Thank you so much for reaching out in regards to your personal hotspot. I am sorry to hear the ports seem to be blocked.


Since it is a wireless hotspot, some ports are unable to be unblocked. You can however unblock ports on a router, unfortunately not for hotspots.


I hope this helps!

I think they are blocking nearly all ports, try this test: Enable the Apache ports in NAT, then on you local machine (have to get the software) nmap -p 80-450 -vv vontobel.dyndns.org, this shows 80 and 443 closed,,, but there.  If you type the same command from another network (coming in from the outside) it doesn't work.  Therefore I think ATT IS BLOCKING ALL THE PORTS.

I am going to assume that you are using a Windows based computer with your iPhone set as the hotspot. Try the following.

(A) Open a DOS prompt box (if you don't know how to do that, find another resource to tell you how). (B) Type ipconfig /release (C) Type ipconfig /renew

This procedure will give your laptop a new "lease" and thus information from the iPhone hotspot on how to get to websites. You can also accomplish the same goal by restarting your computer.
