Check sum Error on create meeting and join meeting

[mohamme...@gmail.com]

Hi Team,

Am trying to integrate bbb with my JAVA application. I used API for create and join meeting everything works good, for sometimes while creating meeting it throws error as "FAILEDchecksumErrorYou did not pass the checksum security check" and same as in join meeting. I couldn't find out on which condition API throwing such error.(Most of the meeting works good on the same code i did)
And i checked bbb-conf --check, there is no potential problem except ip mismatch. Please help me on this


Thanks in Advance

Hi Mohamedh,

Check the nginx log in

  /var/log/nginx/bigbluebutton.access.log

for an entry of the create (or join) API call that is causing errors.  You'll see entries like this

10.0.3.227 - - [15/Dec/2014:22:25:04 +0000] "POST /bigbluebutton/api/create?name=Demo+Meeting&meetingID=Demo+Meeting&voiceBridge=78061&attendeePW=ap&moderatorPW=mp&record=false&checksum=ee890c3949be0afa8e23707b139c18fbf6030216 HTTP/1.1" 200 488 "-" "Java/1.7.0_65"

If you encounter a checksum error, go to the log file and try copying out the message in the URL -- you should still get the same error.

Next, use API Mate, see

   https://code.google.com/p/bigbluebutton/wiki/API#Testing_API_Calls

To try and recreate the API call (enter the same parameters into the form).  

This way, you should be able to create a valid API call with the same parameters and see if there is an error in the calculation of your checksum.

Regards,... Fred
