sslvpn_login_permission_denied

Hello,

 

I have Fortinet 60 F device. An error showed up while trying to connect via SSLVpn that too many bad login attempts.-455 . When I check firewall failed authentication parts I saw that there are a lot of attempts to login. I am adding the screenshot. What can I do as an emergency solution? Thanks in advance.

I have no idea about the cfish user. I don't know whose user it is. I don't have a user like that. I see many logins that are not registered as local users, such as cfish. You can see in the picture. This also causes a warning of too many bad login attempts on the firewall when doing ssl vpn. Please examine the pictures I sent. I think there are too many attacks on my firewall device one after the other and I constantly get failed authentication.
