dropbox.com not opening on wireless with WLC 2504

[networker9]

Hi experts,

I have a setup with flat network wired and wireless using same subnet and a firewall.

Wired and wireless users have same IP subnet.

Wired users are able to access dropbox.com whereas wireless users cant access the site.

Suggestions please.

it resolves the nslookup tracert gives complete reachability but website doesnt open up on any browser.(issue only on wireless)

   - Make sure the wireless users are not blocked for that site , if other sites can be used ; then somewhere a 'filtering device' must be active ,

As a test, tested with allow any any policy for in to out on the firewall..
Result still the same with no luck.

No filtering applied.

 - Have a checkup of the controller configuration using : https://community.cisco.com/t5/networking-knowledge-base/show-the-complete-configuration-without-breaks-pauses-on-cisco/ta-p/3115114#toc-hId-1039672820
              Feed the output into : https://cway.cisco.com/wireless-config-analyzer/

  - Also use client debugging for a client needing dropbox according to https://www.cisco.com/c/en/us/support/docs/wireless/aironet-1200-series/100260-wlc-debug-client.html
   You can have client debugs analyzed with : https://cway.cisco.com/tools/WirelessDebugAnalyzer/

This issue was solved after WLC firmware upgrade.
