    Could not be opened error

      Hi everybody,

       

      Before posting the real question, some things has to be taken into account:

      - We use QlikviewServer x64 v10.00.9061.7 (10 SR3)
      - We connect using the IE plugin tunneled, that is, only the port 80 is opened in the server, it means that port 4747 is closed and always tunnel is checked.
      - When we tried to access using AJAX we haven't found any problems.
      - We have a license with 4 Named CALs assigned to, let's say user1, user2, user3 and user4.

      - Network latency is very good.

       

      And the problem:

      The system works properly but sometimes a werid issue comes up in our access to Qlikview documents, happening randomly. When a user tries to open a document this error message appears:

       

      qvp://SERVER;http/1/dashboard.qvw?iis_authenticate=TICKET&tunneler=http%3A//SERVER/scripts/QVSTunnel.dll%3Fhost%3DSERVER_NAME could not be opened.

       

      Note that SERVER, TICKET and SERVER_NAME are not real values.

       

      Then our user cannot access the document. It happens every now and then without a known reason. After some tries or hanging on a little then user can connect without problems.

       

      Looking into plugin logs I could see that when the connection succeeds it logs:

      2011-09-14 15:11:17 Info Connect .\ClientServerSupport.cpp 2868 Session established OK 0

       

      Whilst when the connection goes wrong:

      2011-09-14 15:00:50 Info Connect .\QVDoc.cpp 3904 Trying Http tunneled connection 0
      2011-09-14 15:00:50 Info Connect .\ClientServerSupport.cpp 2584 Negotiating string: ... [A large XML string]
      2011-09-14 15:00:55 Warning Connect .\ClientServerSupport.cpp 2633 Server did not respond inside timeout: "" 0


      There is a situation where the problem is always found and that is when you connect to the document, close the IE window, open a new window and try to open it again, then you find the error,

       

       

      I don't know what else can be done.

      Thanks in advance.
