Getting 400 bad request error for a url

Hi Team,

We are trying to monitor a url :

http://srvsbjpvlse01.santanderde.corp:50000/irj/portal

with one of our monitoring tools. where we are using curl API's to monitor this url.

However every time we get an error :

root@sanplepamonit01 ~ # curl -I http://srvsbjpvlse01.santanderde.corp:50000/irj/portal --compress --insecure

HTTP/1.1 400 Bad Request

So can you please suggest that what could be wrong over here and how to correct this ?

Any assistance would be much appreciated.
