I'm getting the following error response suddenly to the http server i'm subscribing to :
<html><head><title>Error</title></head><body><br/><br/><h1>HTTP Status 400</h1><p>The request sent by the client was syntactically incorrect ().</p></body></html>
I have not encountered this issue before. I have not changed/configured on my end.
Below is the sample request.
Has someone encountered this same issue before?
