Invalid request error

[rashid4844]

Hi, We have apigee on-prem setup. Today I tried to log in but got this weird error. Anyone can help me to diagnose the issue:
You have attempted to make a request that does not meet our security requirements.
This may indicate that the request was not originated by you.

I had this issue frequently as I bookmarked the login page. If your previous session is still running, you'll get this message. You can continue working by goin straight to the Edge console https://apigee.com/edge.

I replaced my bookmark by the link above, so it shouldn't be a problem anymore.
