This error can occur for the following reasons: the connection was dropped via a DROP STATEMENT, or the database server was shutdown, or the network connection to the database server was interrupted. You can add LogFile=<filespect> to the connection string and -z (with -o <filespec> to capture the output to a file) to enable communications diagnostic logging which can likely help isolate what is happening. If you have questions about the information collected in the logs, please ask or post the files here for comment. It seems to be an HTTP options !? .....

Try Log=<file_spec> where filespec is a path and filename . If you continue to have problems, can you post your connection string (masking confidential info with ***.
