Hello everyone...I am currently facing a problem which error "The page cannot be displayed" while I am uploading data. I am using an excel file to store 5000 mobile number and a line of message which i want to send in the first row. However, when i trying to send, the error message appeared. I had tried to change the session to 2 hour, but the error still pop up in an hour.

I suspect that it is Web Server problem. However i can't confirm it. One more thing to mention is i am not using local connection. My pc and server is in different place. Therefore i am not sure whether is the network problem.

I hope someone can help me to figure out what problem i am facing and i am really appreciate if anyone can help! Thanks in advance.
