File upload throws MethodNotAllowedHttpException

I am facing this strange issue when I try to upload large file (e.g; 70MB) then it throws me MethodNotAllowedHttpException exception. It works smoothly with small sized files. Following is the configuration php.ini file.

upload_max_filesize=1000M
post_max_size=2000M
memory_limit = 3000M
max_file_uploads=200
max_execution_time=30000
max_input_time=30000

Any clue why I am having this issue?
