I was working on my client’s solusvm admin panel that I got kicked out suddenly. I started getting the following message, whatever way I tried to access the admin control panel.
I tried various ways to gain access, but nothing worked. The following trick helped me.
I logged in to the server as root via ssh and whitelisted my IP Address.
Now try accessing the admincp, it would take you to the login page. It worked for me, hope it works for you too !!!
