Avast blocks access to company's intranet-please help

Hello,

Apparently my Avast av (previous version and new version 12.1.2272) blocks access/cannot log in, to my company’s intranet (AFAS InSite). When disabling Avast shields control, I can access/login this intranet. How can I enable access with Avast shields active. (I’m not an Avast pro…)
Thanks in advance.

Is there a block message from avast?
If so, what does it say?

what is the URL

What exact version of avast ? (Free/Pro/IS/Premier)

Hello,

I’m using IE11. I never had problems accessing the intranet before, it all started after my company moved its systems to "a cloud’…
Now, when I try to log in with my user name and password, the empty inlog screen keeps popping back.
@Eddy: I’m using the latest Avast Free 12.1.2272

I just noticed this login problem only occurs with IE11. I can login without any problems and all Avast shields on with Mozilla Firefox en Google Chrome. So apparently it’s a Windows10/IE11.0.32/Avast issue… :-\
