• No connection could be made because the target machine actively refused it? 23 answers

My Asp.net application is working well on local except a particular area of code. When I am trying to get detail value of a record it throws an exception "No connection could be made because the target machine actively refused it 127...1:62***". I checked all the possible way but if you have any suggestion let me know.

error on this line Line 93: response = cl.DownloadString(handler);
