My application doesn't work since I changed the url of the web service

Since August 1st, the url of the web service changed, the application was running fine with the previous url, but with the new one, the application works for 1 user, the 2 other ones encounter this error message :

Could not establish trust relationship for the SSL/TLS secure channel with authority 'e-factura.sunat.gob.pe'

My project is a console one, in it, I use a certificate file to sign a xml file, the certificate is on a server, it's not installed on the certificate store. Moreover, to consume the web service, a wsse:security authentication is required. My app.config file is this one (I did hide the wsse:security credentials) :

I have no idea what to do to solve the problem, moreover, I can't consume the web service on my machine (the web service is used to sent real invoices to tax office). Thanks

Why dont you add some logging into your app which logs what is happening during the process.

You should be able to see if anything is different between the user that it is working for and the 2 that it is not.

If nothing is different this may suggest that there is a permissions issue with those 2 users.

Here is my code to consume the web service :

Code:

---

System.Net.ServicePointManager.UseNagleAlgorithm = True
System.Net.ServicePointManager.Expect100Continue = False
System.Net.ServicePointManager.CheckCertificateRevocationList = True

Dim data As Byte() = System.IO.File.ReadAllBytes(global_zipToSend)
Dim MyReturn As Byte()
ws.ClientCredentials.CreateSecurityTokenManager()
ws.ClientCredentials.UserName.UserName = userName
ws.ClientCredentials.UserName.Password = pwd

Try
    ws.Open()
    Console.WriteLine("open")
    MyReturn = ws.sendBill(l_nombre, data)
    Console.WriteLine("close")
    ws.Close()
Catch ex As Exception
    Throw New Exception(ex.Message)
End Try

But I tend to think the error is related to the certificate itself but I'm not sure

Hello guys,

I ran Internet Explorer on the server, I added the web address of the web service as a trusted site, I asked users to the same, so far, I got a feedback from 1 of them who confirms the call of the web service is now working.
