There is something wrong with your login cookie:
[Warning]: [RFC.ParamountPlus.AccountStore] [ERROR] FetchSessionLoginCookie: login failed/parse error
[Warning]: [WV.ParamountPlus] RequestSessionToken: login failed, abort
[Warning]: [WV.ParamountPlus] INTL at_token failed, retrying with FR at_token
[Warning]: [WV.ParamountPlus] DAI API request failed - returnCode: -105 size: 0
Try signout and relogin and if that doesn’t help:
Close,SF and rename directory cache in:
%AppData%\DVDFab\StreamFab\rootCachePath
then re-login, close tab and try again
(re-login is then required for all providers)
If this doesn’t help (problem after update?) try
a complete uninstallation and reinstallation.

btw: Using a VPN ?
