c# - An unexpected error occurred on a send. EOF or 0 bytes from the transport stream -

i make request https site code:

 webrequest = (httpwebrequest)webrequest.create(new uri(urldestination));             webrequest.method = "post";             webrequest.contenttype = "application/x-www-form-urlencoded";             webrequest.contentlength = bytes.length;              stream writer = webrequest.getrequeststream();             writer.write(bytes, 0, bytes.length);             if (writer != null)             {                 writer.close();             }              response = new streamreader(webrequest.getresponse().getresponsestream()).readtoend(); 

and error:

i after checking on web error found solution , didn't worked:

servicepointmanager.securityprotocol = securityprotocoltype.ssl3; 

after taking supplier said encountered error

ssl_do_handshake() failed (ssl: error:1408a0c1:ssl routines:ssl3_get_client_hello:no shared cipher) while ssl handshaking 

i know error part don't know how make request skip error.

the ssl3 statment did solve issue, came across suggestion didn't apply me since have content length statement.

the suggestion remove statement.

my working code follows:

//create webrequest uri jsonuri = new uri(new uri(jirainstanceuri), serviceuri); webrequest restwebrequest = webrequest.create(jsonuri); restwebrequest.method = "get"; restwebrequest.contenttype = "application/json"; //add proxy webrequest proxyserver.bypassarraylist.add(jsonuri); restwebrequest.proxy = proxyserver; //setup authorization string base64credentials = getencodedcredentials(username, password); restwebrequest.headers["authorization"] = "basic " + base64credentials; servicepointmanager.securityprotocol = securityprotocoltype.ssl3;
