Admin Page logon loop

I've deployed a FortiManager 5.4.5 VM in my Hyper-V test environment and every time I logon I always get sent back to the logon page. 
 
I have tried changing the password in the CLI (locally on the VM) and logging on with that but it still has the same issue - I cannot login.  
 
What is strange is that when I present the wrong credentials it tells me they are wrong, however when I enter the correct ones I am looped back around to the login page. 
 
I've tried Chrome and IE and it has the same issue. 
 
I'm stuck and frustrated! Does anyone have any tips for browser configuration or have seen this before and know the fix?

    Hi  Tom,
    Does it happens when you are login through the HTTP only? It works ok with HTTPS, right?
    Perhaps http-redirect is disabled?
     
    Try to enable it if it disabled:
    #config sys admin setting
    #set admin-https-redirect enable
    # end
     
    Cheers,
    Tsvetan

    Thanks for the reply, Tsvetan. 
     
    It seems the auto redirect is enabled by default - something I hadn't noticed until your post.  Therefore when I launched the page I was automatically directed to https. 
     
    I have used your commands to disable the https redirection, there to test on http to see if that helps but sadly I am still in a loop. 
     
    Any other tips or tricks would be appreciated!

    Hi,
     
    Sadly I didn't find a solution for this. It was only in my lab so I just sacked it off.  I don't know if a newer version of the VM would help.  I'm also not sure if it's worth banging the VMware one in to see if it's an "image thing" or a problem with my PC and its configuration. 
     
    If you get anywhere with it then please let me know.

    A possible laundry list of things to check/try:
    • Confirmed the time/timezone on the VMHost is set correctly/same with the FM.
    • Check/confirm the correct security certificate is correct/found. (This came up recently and I think is what papapuff is referring to.)
    • Check your user ID is assigned the correct adom/admin profile; Likewise, check the admin profile to see if it is correctly setup.
    • Check the system event log for possible clues.

    Being most of these seemed to happen after daylight savings kicked in, check the times on both your host and the 40gate and confirm they are the same. The 40gate will kick you out after x minutes of inactivity and if daylight savings is on the 40gate and your system is an hour behind, hello kick out!

    Hello, i've managed to solve the problem. I mean it solved itself
     
    It may not be able to help you but, i restarted the fortigate via console but it doesn't solve the issue and then i leave it for a couple day i guess, and it went back to normal. I don't know what exactly why. But i was taking a guess that the device is penetrated by someone by bruteforce. It's because i put an ip public to the wan interface and expose the fortigate web administration portal which is running on port 80. And then before the restart, i modified the web portal to port other than 80.

    Check the properties of the VM for the processor and the memory of the license.
    Try reload licens file use CLI.

    I've just found out I had this issue, and it was caused by our Trend proxy.  Disabling the proxy in IE settings solved the issue for me...hopefully can help you too!

    Hey, i just have the same issue on a product, fortianalyzer 6.0.1, basically i tried different configuration. Finally i was able to resolve the issue, is related to the certificate ssl, you have to download first from web admin console, install on your browser and install as trusted root authority also. You can now login correctly :). It's probably a sort of Man in the middle attack detected by the firewall and you go in loop. But installing certificate ssl you resolve it. Hope this help. Cheers

    Hey install certificate download from web gui, install double click on cert, and install as trusted root authority. This finally resolve the issue. Is a man in the middle protection that will going in loop. Cheers

    Additional information: If you reboot your fortimanager/fortianalyzer, you have to do again the procedure to reinstall the certificate. I don't know exactly why, since the certificate is the same, is not newly generated, but you still have problem of loop if you reboot. 
     
    I tried to install again the certificate, and work properly.
    Btw i will update the firmware, since this seems to be instable from this point of view (login).
