When adding a web reference to a visual studio 2019 web service project I am getting the following errors:
" - The underlying connection was closed: An unexpected error occurred on a send.
Authentication failed because the remote party has closed the transport stream."
and
"The custom tool 'MSDiscoCodeGenerator' failed. Unable to import binding 'Soap11' from namespace http*****"
The server offer three webservices, first web service worked perfectly no issues. The second brings up these errors.
I suppose my question is, seeing as this looks like configuration on the third parties end, is this a visual studio error?
All WSDL offerings from the server work perfectly in the browser and in SOAPUI

I have a blazor server application developed and published with .Net 6 that runs on a windows server 2019 and uses a ASP.Net 4.8 web service. One of mothods of web service takes approximatly 45 seconds to be executed. During calling this web method I encounter with an exception as follows:
---> System.Net.Http.HttpRequestException: An error occurred while sending the request.
---> System.IO.IOException: Unable to read data from the transport connection: Eine vorhandene Verbindung wurde vom Remotehost geschlossen..
In this case there isn't any error in web service and the exception occures because of long response time of web method.
On the other hand I Have a test server that have exactly the same hardware characteristics as the last one. It's OS is also windows server 2019, and the only difference between two servers is that on test server, I have installed Visual Studio 2019 because of testing purposes. On this server, the blazor app calls the web method without any problem, although it take also a long time to return.
I don't know why this error occurs in the first case. Are there any dependencies I need to provid? I suspect it is due to installed VS2019 that there is no error on the test server.
How can I check, what dependencies I need to install on product server to avoid this exception?
Im trying to add wsdl web service in windows form application to connect a web service. It gives error of

I checked the similar questions but they didnt help. How can i get out this issue. im using Windows 10, Visual Studio 2013
Any help is appreciated.
I am trying to deploy my webapp VS2015 RC1 DNX 451. Even when I validate connection and run publish I get error
Severity Code Description Project File
Error Error Code: ERROR_USER_UNAUTHORIZED
Error More Information: Connected to the remote computer ("crocus.arvixe.com") using the Web Management Service, but could not authorize.

Error Error: The remote server returned an error: (401) Unauthorized.
Googling the issue and even trying to view host forum just says make sure username and password is correct. I am getting nowhere trying various settings. Any ideas how to debug the issue?
I am using Arvixe.com as host.
You should contact Arvixe.com. They likely have some odd configuration on their servers but I would suspect they can help you resolve the issue.
Arvixe does not support Web Deploy anymore. Once they move you to their new servers Web Deploy won't be available to you. In Visual Studio you can set up a Publish with FTP instead of Web Deploy. If you're used to Web Deploy publishing your database changes, then you'll need to do those yourself with SQL scripts. Entity Frameworks has an option to produce a SQL script for a migration, so you can use that to publish your EF database changes.
I’m having trouble adding a reference to an HTTPS web service using Visual Studio 2008, it works fine in Visual Studio 2010 but in VS2008 I get the below error.
Our IT guys tell me that the problem is that VS2008 is not using the IE proxy settings properly so the HTTPS request is getting sent to the HTTP proxy, which always denies all HTTPS requests. However, in VS2010 it works just fine.
They don't know how to fix this if that is indeed the problem.
(As an aside, I have to use VS2008 because I want to use this in an SSIS Script Task, however I've been testing this in a blank console app.)
There was an error downloading 'https://xxxxxxxxxxxx.asmx'.
The operation has timed out
Metadata contains a reference that cannot be resolved: 'https://xxxxxxxxxxxxx.asmx'.
An error occurred while making the HTTP request to https://xxxxxxxxxxxxxxxxxxx.asmx. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server.
The underlying connection was closed: An unexpected error occurred on a send.
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
An existing connection was forcibly closed by the remote host
If the service is defined in the current solution, try building the solution and adding the service reference again.
This appears to be a bug in Visual Studio.
Background: I've been tasked with creating a single sign on solution which will redirect our internal users to a vendor's web application. I've set it up as an ASP.Net project which will call a web service provided by the vendor. This service will return a URL and a token to be used to sign in to the vendor's site. All this is to be done securely.
Problem: When using Visual Studio's Add Web Reference dialog to download the WSDL and generate the required proxy class, I get the following error:
There was an error downloading
'https://server:port/folder/Service?wsdl'. The
underlying connection was closed: An unexpected error occurred on a
send. Authentication failed because the remote party has closed the
transport stream. Metadata contains a reference that cannot be
resolved:
'https://server:port/folder/Service?wsdl'. An
error occurred while making the HTTP request to
https://server:port/folder/Service?wsdl. This
could be due to the fact that the server certificate is not configured
properly with HTTP.SYS in the HTTPS case. This could also be caused by
a mismatch of the security binding between the client and the server.
The underlying connection was closed: An unexpected error occurred on
a send. Authentication failed because the remote party has closed the
transport stream. If the service is defined in the current solution,
try building the solution and adding the service reference again.
In addition to this error, the Add Reference button is grayed out, preventing me from adding the reference and generating the proxy class.
The project is running under .Net Framework 4.0. I've downloaded and installed the necessary client keys/certificates correctly. I've added the IP address and server name to the hosts file and added both to the proxy bypass list. I can browse to the endpoint and view the WSDL in IE and VS's web browser. I can even view the WSDL in the Add Web Reference dialog box in VS. In each case, I'm prompted to select which certificate to use, which I do.
I do not have access to the web service itself or the server it is located on.
I've spent many hours on Google, but have not been able to find a resolution. Any ideas?
Worked around the issue by downloading the WSDL and pulling it into VS through the Add Web Reference dialog by referencing the URL file:\\\drive:\pathname\filename.wsdl.
