You can use Mconf's BBB API Mate (http://mconf.github.io/api-mate/) to test out the raw calls to see which ones are failing. You just have to plug in your salt and server info.

Also, what are you getting back when you run "bbb-conf --check"?

Hi Fred, 

Thanks for your revert again. I tried filling all the information related to server and salt and i am getting error 504 while accessing the api.

Also please find below the command "sudo bbb-conf --check"

Hi, 

Thanks for your revert again. I tried filling all the information related to server and salt and i am getting error 503 while accessing the api.

[Chad Pilkey]

Both codes basically mean that the service (bbb-web) was unavailable. Have you made any manual changes to configuration files? The result from "bbb-conf --check" shows that the wrong IP is set in one of the files.

[aayush kamboj]

no i did not made any changes related to IP. i just followed the upgrading information given in the bbb doc for 0.9 to 1.0

[aayush kamboj]

i have made change in "/usr/share/red5/webapp/sip/WEB-INF/bigbluebutton-sip.properties" now. i replaced the the public ip with localhost 127.0.0.1 and clean the bbb. i am getting the below response now on check command.

bbb@ubuntu:/usr/share/red5/webapps/sip/WEB-INF$ sudo bbb-conf --check

# Warning: The API demos are installed and accessible from:

#

#    http://69.64.94.183/demo/demo1.jsp

[Chad Pilkey]

Can you try running "bbb-conf --clean" which will restart everything and clean out the old log files. Then access the API. Then check "bbb-conf --debug".

The last command will hopefully  output an error message that can help track down the issue.

[aayush kamboj]

Ran the clean command but got the same response again

Please find below logs of debig command.

bbb@ubuntu:/usr/share/red5/webapps/sip/WEB-INF$ sudo bbb-conf --debug

[Chad Pilkey]

That's the extent of my knowledge about bbb-web unfortunately. Everything looks fine on the surface, but it's still returning at 503 and I'm not sure what the potential scenarios are that could cause it.

[aayush kamboj]

Thanks for the help

@Fred Need your support here. Please help. 

[Fred Dixon]

Hi Aayush,

I just did a quick test on your server and was able to login to one of the demo meetings -- Did you resolve the issue.  What did you change to make the login from the API demos work?
