Business Objects 4.1 SP 6 Patch 6 on Windows Server 2012R2.
Tomcat for Web Intelligence

We have two users who are not able to access the Web Intelligence (LaunchPad) log-in page in our UAT environment. There receive the generic ‘The webpage cannot be found’. All other users are working just fine. This is not a BO Permissions issue, as this just stopped working for them. We are all on the same equipment running Windows 7 with Internet Explorer 11. These two users are able to login if we use the LaunchPad page for Production environment and change the system name to UAT. Any ideas?

Can they access the default tomcat page? (http://server:8080) If not, then it's an issue with network connectivity. Check the firewall on the client and/or server.

Joepeters, thank you for your response. Since I posted this yesterday, we had done some additional testing.

Yes, the two users can get to the default tomcat page. They are able to access BO LaunchPad using the IP Address. Both of these users just started experiencing this issue recently. They were able to successful access Launchpad. All updates (OS and Application) are pushed to all computers so there are no differences there between those than can access the page and the two that cannot. They are able to ping the page successfully and nslookup returns the expected results (same as what I return). Our PC and network firewall protections are also universal across all users and are locked down. Our network guy is also perplexed with this issue.

Interesting that they can get to the default Tomcat page but not BOE. I'm assuming you had them clear their browser cache?

Have you tried another browser?

You might need to install a web traffic analyzer, like Fiddler, to see what's going on.

Few queries:

Do you have SSO turned ON for BI Launchpad? If yes, can the two users login using NonSSO Login?

With the IP address in URL; can the users login manually?

Thank you for responding...

Joepeters – yes, clearing the browser cache was one of the first things I had them complete. We get the same results with Google chrome (IS and Chrome are the only browser permitted in our environment).

Viru4808 – SSO is turned on for BI Launchpad. No they cannot use non SSO as they do not get a login page at all. We have also tried using the IP Address which brings up the login page and allows them to login. We have even tried using the FQDN and still no luck.

Can you please check if this is configured correctly:

Navigate to <Installation\SAP BusinessObjects\tomcat\conf> and edit the server.xml file. Find the Connector Port 8080:

maxHttpHeaderSize=”65536”

Also, set the JAVA_OPTS for tomcat:
-Xmx2048m

if it works with other browsers for those users, you could try the suggestions given here:-

Has anyone found a solution to this problem? If so, can you note it here?

I am getting the same "The webpage cannot be found" issue at SSO login on one account out of hundreds. Just started last week. Issue is only affecting this one account and the issue will follow the account across browsers and to different computers.

The fix that worked for me was to update the C:\Program Files (x86)\SAP BusinessObjects\tomcat\conf\Server.xml file and add “maxHttpHeaderSize="65536”” to the connector entry.
Then rebooting or restarting the web services.

Best Regards,

we are having the same issue and occurring to some users only. verified the maxheader size 65535

I set the following registry keys:-
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\LSA\Kerberos\Parameters
LogLevel 0x00000000 (0)
MaxPacketSize 0x00000001 (1)
MaxTokenSize 0x0000ffff (65535)

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters
MaxFieldLength 0x0000fffe (65534)
MaxRequestBytes 0x0000ffff (65535)

restarted all servers. no luck. removed cache from users machines too..

Hi. Thanks for the reply. I am aware of the cgrome issue. but here what I mentioned is not related to chrome's issue. Bi launch pad link is not opening for only 4-6 users.

So it's either their browser, or their network connection. get them to try another browser, and if that doesn't work, take a laptop that you know works over to their location and test from their network connection.
