Based on your on-premise environment configuration after upgrade to KanBo 2.2 you can face following issue:

Module: WindowsAuthenticationModule
Notification: AuthenticateRequest
Handler: PageHandlerFactory-Integrated-4.0
Error Code: 0x80070021

Config: Error This configuration section cannot be used at this path. This happens when the section is locked at a parent level.

Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with ="Deny" or the legacy allowOverride="false".
Config File: \\?\C:\inetpub\wwwroot\\web.config

The error occurs in line 196:
<windowsAuthentication enabled="false" />
