Cant login from the server

[digichap28]

Hey there! 

I'm testing some stuff and this time I tried to log in to the Qlikview accesspoint from the same server Qlik is deployed, but I couldnt. Do you know why this happens ? BTW... I can login from a remote client using the same credentials.

I get a 401 - unauthorized http error every time I submit the windows authentication form with my credentials.

The request header:

GET /qlikview HTTP/1.1
Host: myhost.com
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:78.0) Gecko/20100101 Firefox/78.0

The response header:

I still can't login from the server. Anyone knows what can be happening ?

Hi 

Can you provide more information. 

1. Were you able to login before?

2. Do you have a Qlikview license (User Cal or Doc Cal)?

3. Do you have access to the folder where .qvw file is saved?

4. How is section access implemented on .qvw file?

Please note you can have access to server for development but it does not imply automatic access to portal (access point)

Hi CJ29

1. Were you able to login before?

This is the first time I try to login to the accesspoint using a browser installed on the QV Server. 

I can login from any other client machine.

2. Do you have a Qlikview license (User Cal or Doc Cal)?

I tried using different users with Named and Document.

3. Do you have access to the folder where .qvw file is saved?

I do. I can open them without any issues.

4. How is section access implemented on .qvw file?

There is no section access implemented on this app.

Found the solution 😊 !!

There are 2 possible workarounds, but this one below is the recommended one.

1. Click Start, click Run, type regedit, and then click OK.
2. In Registry Editor, locate and then click the following registry key:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0
3. Right-click MSV1_0, point to
   New, and then click Multi-String Value.
4. Type BackConnectionHostNames, and then press ENTER.
5. Right-click BackConnectionHostNames, and then click Modify.
6. In the Value data box, type the host name or the host names for the sites (ex. hostname.com) that are on the local computer, and then click
   OK.
7. Exit Registry Editor, and then restart the server for this change to take effect.
