Cannot login to SonicOS web-based management interface via HTTP after upgrading to SonicOS 5.8
12/20/2019 13 13537
Beginning in SonicOS 18.104.22.168, HTTP access to the SonicOS web-based management interface is disabled by default. When running SonicOS 22.214.171.124 using factory defaults, the administrator can log into the management interface using HTTPS at https://192.168.168.168. HTTP management is still allowed when upgrading from prior firmware versions, when already enabled in the previous configuration settings.
NOTE: HTTP management must be enabled when the firewall is being managed by SonicWall GMS via a VPN tunnel. This applies when using either a GMS Management Tunnel or an existing VPN tunnel.
The System | Administration page has a new Allow management via HTTP checkbox to allow the administrator to enable/disable HTTP management globally.
