The application fails to open and start up. What are the possible reasons?

The application may not open or give errors while logging due to various reasons. A few of the reasons are listed below: - The connection is dropped by the server. A non-supported HTTP version or format is used. HTTP 1.0 does not issue Status Lines that begin with "HTTP/1.1", so if you expect a different version and it is not there, then this would be an Exception (to the rule). Packets are being dropped without retransmission from the server. Non-Implemented Method (GET, HEAD, POST, TRACE, DELETE, PUT), if you expect to get a POST and in reality get a TRACE, then the line will be different and could possibly cause an error. A timeout or connection is reset. When the socket gets closed, it will wait for the internal buffer to be delivered to the receiver instead of closing immediately and possibly losing data.
