Troubleshooting Portal Access Resources

Hi DevCentral,

 

I had a number of portal access resources configured to allow me access to internally configured web applications from outside the network via APM. It all worked. Today, some of them (not all) seem to be failing. Where would I start the troubleshooting of this?

 

I'm looking in /var/log/apm but cant seem to find anything useful there.

 

When I click the portal access apps, Internet explorer comes straight back with 'This page cannot be displayed' it tried going to https://MyAPMAddress.com/f5-w-RandomString which is what it normally does, but the apps arent firing.

 

Thanks

    It's under Virtual server settings under Acceleration settings. If yes you may try to clear ramcache.

     

    tmsh delete ltm profile ramcache all

    Hi Kunjan,

     

    its set to optimized-caching.

     

    i tried deleted the ramcache, but still the same issue.

     

    really confused, as I said, all my portal apps where working. The actual apps continue to work if I go to them directly when connected to my LAN.

    May be can try to take out the web acceleration (None).

     

    To troubleshoot further, enable logging for portal access with information/debug and check the logs at the logs under /var/log/rewrite*

    Hi Kunjan,

     

    I tried taking out the Web Acceleration but that didnt help. Enabled the logging for portal access and have copied a snippet of the logs (i couldnt the copy all of it as it was being identified as spam) during an attempted access below. Could the issue be to do with this line:

     

    headerValues: Not found for uri:/
