Can't see webpage on AWS installation

#1

I need a Guru!
I installed the latest and greatest version of opendronemap last night on to an AWS vm. After competion (about 1 hour, 15 min) I saw the “happy” message:

Congratulations! └@(・◡・)@┐

==========================

If there are no errors, WebODM should be up and running!

Open a web browser and navigate to http://3.81.229.187

Clearly something went south on the install with that address.
I ran netstat -anc to see what port may have actually been used in the process.
I found NodeODM on port 3000 – this is running without issue.

The only other ports that are open/listening, 6006 , which is tensorboard–and working
8500 and 8501.
On 8500 I get the message:

This page isn’t working

compute-1.amazonaws.com** sent an invalid response.

ERR_INVALID_HTTP_RESPONSE

… and on 8501, I get the message:

Not Found

… I am so green to AWS installs, I can’t find the logs–does anyone know where I should look? Any ideas on what the story might be?

BTW, I also did a restart on all the services:
sudo service nodeodm restart
sudo service webodm-nginx restart
sudo service webodm-gunicorn restart
sudo service webodm-celery restart
sudo service webodm-celerybeat restart

… no errors… no messages.

Please run netstat -tapn | grep LIST and paste the output here.

And also firewall-cmd --list-all-zones, or iptables -L -n depending on what you’ve got.

ITWarrior,
Thanks for responding. I really do appreciate it. Here’s what netstat yields

tcp 0 0 127.0.0.1:6379 0.0.0.0:* LISTEN -
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN -
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN -
tcp 0 0 127.0.0.1:5432 0.0.0.0:* LISTEN -
tcp6 0 0 :::8500 :::* LISTEN -
tcp6 0 0 :::8501 :::* LISTEN -
tcp6 0 0 :::6006 :::* LISTEN 20813/python
tcp6 0 0 :::22 :::* LISTEN -
tcp6 0 0 :::3000 :::* LISTEN -

At first pass, neither firewall or iptables seems to be installed on this AWS image.
