There was no endpoint listening at url that could accept the message

Question

I m building an ASP NET website - it s a solution with a few projects  a data base and a web service  Everything worked fine  but last time I tried to run the project  I got the following error   There was no endpoint listening at http   localhost  number  BooksWS svc that could accept the message  This is often caused by an incorrect address or SOAP action  See InnerException   if present  for more details    The inner exception says   Unable to connect to the remote server   This error sort of came out of the blue  so I m not sure what additional information I should provide  Does anyone have any idea why this could happen   I suppose even a general answer could help  the only info I found about this error in the web concerned WCF

This is ancient history but I just ran into this issue and the fix for me was recycling the application pool of the website in IIS   Easy fix  for once

I had this problem when I was trying to call a WCF service hosted in a new server from a windows application from my local  I was getting same error message and at end had this  No connection could be made because the target machine actively refused it 127 0 0 1 8888   I donot know whether I am wrong or correct but I feel whenever the server was getting request from my windows application it is routing to something else  So I did some reading and added below in Web config of service host project  After that everything worked like a magic    lt system net gt       lt defaultProxy enabled  false  gt       lt  defaultProxy gt   lt  system net gt

I solved it by passing the binding with endpoint   http   abcd net SampleFileService svc basicHttpWSSecurity

go to webconfig  page of your site  look for the tag endpoint  and check the port in the address attribute  maybe there was a change in the port number

An another possible case is make sure that you have installed WCF Activation feature   Go to Server Manager   Features   Add Features

Another case I just had - when the request size is bigger than the request size set in IIS as a limit  then you can get that error too   Check the IIS request limit and increase it if it s lower than you need  Here is how you can check and change the IIS request limit    Open the IIS Click your site and or your mapped application Click on Feature view and click Request Filtering Click - Edit Feature Settings      I just found also another thread in stack IIS 7 5 hosted WCF service throws EndpointNotFoundException with 404 only for large requests

I changed my website and app bindings to a new port and it worked for me  This error might occur because the port the website uses is not available  Hence sometimes the problem is solved by simply restarting the machine -Edit- Alternative  and easier  solution reference  Get PID of process which is using the port CMD command- netstat -aon   findstr 0 0 80    Use the PID to get process name -  tasklist  FI  quot PID eq  quot    Open task manager  find this process and stop it    Note- Make sure you do not stop Net tcp services

If you are using custom binding  please make sure that you are putting the same name for both custom binding  Server and Client in config files   lt bindings gt   lt customBinding gt    lt binding name  BufferedHttpServerNoAuth  closeTimeout  00 10 00  openTimeout  00 10 00  receiveTimeout  00 10 00  sendTimeout  00 10 00  gt             lt gzipMessageEncoding innerMessageEncoding  textMessageEncoding  MaxArrayLength  10485760  MaxBytesPerRead  31457280  MaxStringContentLength  102400000    gt             lt httpsTransport hostNameComparisonMode  StrongWildcard  manualAddressing  False  maxReceivedMessageSize  31457280  authenticationScheme  Anonymous  bypassProxyOnLocal  True  realm    useDefaultWebProxy  False    gt   lt  binding gt   lt  customBinding gt   lt  bindings gt    the binding name  BufferedHttpServerNoAuth  should be same in both   Hope this would help someone

I tried a bunch of these ideas to get HTTPS working  but the key for me was adding the protocol mapping   Here s what my server config file looks like  this works for both HTTP and HTTPS client connections      lt system serviceModel gt       lt protocolMapping gt         lt add scheme  https  binding  wsHttpBinding  bindingConfiguration  TransportSecurityBinding    gt       lt  protocolMapping gt       lt services gt         lt service name  FeatureService  behaviorConfiguration  HttpsBehavior  gt           lt endpoint address  soap  binding  wsHttpBinding  contract  MyServices IFeature  bindingConfiguration  TransportSecurityBinding    gt           lt endpoint address  mex  binding  mexHttpBinding  contract  IMetadataExchange    gt         lt  service gt       lt  services gt       lt behaviors gt         lt serviceBehaviors gt           lt behavior name  HttpsBehavior  gt             lt serviceMetadata httpGetEnabled  true  httpsGetEnabled  true    gt             lt serviceDebug includeExceptionDetailInFaults  true    gt           lt  behavior gt           lt behavior name    gt             lt serviceMetadata httpGetEnabled  true  httpsGetEnabled  true    gt             lt serviceDebug includeExceptionDetailInFaults  false    gt           lt  behavior gt         lt  serviceBehaviors gt       lt  behaviors gt       lt bindings gt         lt wsHttpBinding gt           lt binding name  TransportSecurityBinding  maxReceivedMessageSize  2147483647  gt             lt security mode  Transport  gt               lt transport clientCredentialType  None    gt             lt  security gt           lt  binding gt         lt  wsHttpBinding gt       lt  bindings gt       lt serviceHostingEnvironment multipleSiteBindingsEnabled  true    gt     lt  system serviceModel gt

Try this    Delete the service instance  Create a new instance of the service    Sometimes the port is changed and generated error

Short answer but did you have Skype open  This interferes specifically with ASP NET by default  and localhosts in general  using port 80   In Windows  Go to Tools -  Options -  Advanced -  Connection and uncheck the box  use port 80 and 443 as alternatives for incoming connections
