If you see the message with "Forbidden, Invalid authenticity token" when you try to login the Edgecore Customer Support portal(as below picture)
This is because system need your browser to allow 3-party cookie.
Below I use google chrome as example to enable the 3-party cookie.
1. Open setting page.
2. Find Private & safe
3. Choose "allow all cookie" to allow all 3-party cookie
And you should be able to login now.
Notice that IE Explorer is not support in our system.
Please use other browser, like Chrome, Firefox, Safari, etc.
