Cannot access web-management or captive portal

  • 1.  Cannot access web-management or captive portal

    Posted Mar 02, 2018 09:43 AM

    Hello,

     

    Yesterday captive portal on our controller 7205 stopped working. I tried to login to web management and it's not working either. Tried with different browsers and computers.

     

    APs work with radius client's normally.

    SSH to controller works.

     

    Controller has been restarted.

     

    What should i try to get web-management (and captive portal) to work again?

     

    Any help would be appreciated.

    ssh into the controller and type "show audit-trail" to see what might have been changed.

    audit trail shows only one line from yesterday:

    webui[3870] 23:57: USER: Error Executing the Command.

     

    no earlier changes.

    What version of ArubaOS are you running? Is the CWP/GUI secured with a certificate? The default certificate which has been shipped with controllers has been revoked so this maybe an issue.

    Do you see any issues when running the below command?

     

     # show web-server profile

    Have you tried restarting the service as well?

     

    #process restart httpd

    Has there been any firewall policies been applied to the management ports on the controller?

    ArubaOS 6.5.3.0

     

    # show web-server profile

    Seems to be ok to my understanding...

    Web Server Configuration
    ------------------------
    Parameter                                          Value
    ---------                                                  -----

    SSL/TLS Protocol Config                    tlsv1 tlsv1.1 tlsv1.2
    Switch Certificate                                default
    Captive Portal Certificate                    wlan2
    IDP Certificate                                    default
    Management user's WebUI access method              username/password
    User absolute session timeout <30-3600> (seconds)  0
    User session timeout <30-3600> (seconds)           900
    Maximum supported concurrent clients <25-320>      75
    Enable WebUI access on HTTPS port (443)            false
    Web Skype4B Listen Protocol/Port Config            N/A
    Enable bypass captive portal landing page          false
    Exclude Security Headers from HTTP Response        false

     

    # show web-server statistics 

    Error in fetching statistics, Web Server is not respoding

     

    #process restart httpd

    I've tried to restart httpd and doesn't seem to help. (also restarted controller) 

     

    Captive portal has valid certificate from public ca.

    To be honest i'm not sure about webgui certificate.Only logged on using ip-address.

    No firewall policies on management ports.

    Looks like the Web Server has stopped responding.

     

    # show web-server statistics 
    Error in fetching statistics, Web Server is not respoding

    This is still the same issue after a reboot and a httpd service restart? This might be a known issue with the OS you are running. Maybe speak to TAC or check the release notes for a possible fix.

    How long ago did you change the Captive Portal Certificate?

     

    Try changing it back like this:

     

    config t
    web-server profile
    captive-portal-cert default

     

    Nevermind.  Please open a TAC case.

    Cert was installed 8-9 months ago.

     

    I tried changing to default and restarted httpd but issue still remains.

     

    Thank you for the help anyway.

    What do you see in the browser when you try to browse to the controller's web page?

    IE:

    "This page cannot be displayed"

     

    CHROME:
    "This site cannot be reached"
    ERR_CONNECTION_REFUSED

    What is the URL?  Does it redirect to https://<ip address>:4343/URL?  What is the URL without the ip address that it fails on?



  • 13.  RE: Cannot access web-management or captive portal

    Posted Mar 02, 2018 01:00 PM

    i've tried with both:

     

    https://<ip address>:4343

    and 

    https://<ip address>

     

    Both give same error.

     

    URL used to work with https://<ip address> 

    (i had it bookmarked on management workstation)

     

    If i understood your question...
