                      VOLTTRON Simple Web agent

                      Asked 2021-Oct-05 at 14:19

                      On release 8.1.1 I am trying to experiment with the simple web agent.

                      Running through the setup process

                      volttron -vv -l volttron.log --bind-web-address http://0.0.0.0:8080 &
                      

                      Everything seem to install OK for http protrocol on the vcfg and starting the agent starts fine but going to the browser I get an empty page response.

                      And in terminal an error here's the Full traceback:

                      EDIT

                      So if I do a nano ~/.volttron/config it looks like this below. I did change the bind-web-address for the IP address of my test bench instance. Hopefully that wasn't a mistake it looked like the initial bind-web-address was the name of the computer. --bind-web-address http://ben-hp-probook-6550b:8080

                      message-bus = zmq
                      vip-address = tcp://127.0.0.1:22916
                      instance-name = benshome
                      bind-web-address = http://192.168.0.105:8080
                      web-ssl-cert = /home/ben/.volttron/certificates/certs/platform_web-server.crt
                      web-ssl-key = /home/ben/.volttron/certificates/private/platform_web-server.pem
                      web-secret-key = 0e3b19770c0a8c0a08f274fcdabaf939fecc16601283266934c5ab258a1ed20cf440fde2c83cb8660dac569d31b5cdaf3ab7354a39b0640f355f9c5407c5fce619
                      

                      I think I did first try HTTPS then resorted to HTTP. Anyways when I start VOLTTRON do I still need a --bind-web-address arg if the ~/.volttron/config is already setup with one?

                      I've a tried both when starting VOLTTRON to use the --bind flag or not but still unable to bring up a webpage on the IP address of the machine running VOLTTRON of 192.168.0.105. This would be the simple web agent, right?

                      I was able to reproduce this when I ran through vcfg and specified https, but then did what you did and passed the bind-web-address to the volttron command itself.

                      However, you shouldn't do this. The instructions assume you haven't gone through the vcfg process and therefore you would have to specify the bind web address on the command line.

                      Since you went through the vcfg process your config file (~/.volttron/config) will have your hostname:port as the bind-web-address. If it has https in it that is the reason it is not working for you.
