broadcast message

hi, experts ,

am working on Broadcast messages in CRM4.0 with webclient,

i can send BM messages in my production client , but when it comes to my QA clients it is not displaying ,

as i found that there is a port number in the URL , this port number is 8000 in my PROD client,

but in QA client i have 50000,

when i sent BM in prod client i can see the messages ,

so for the QA client i did change the port number for the URL and i used it , but no messages displayed,

regards
