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).
