Epicor Web Access (EWA) can't login

I can get to the EWA login form from a browser but after entering credentials the displayed page just goes back to a blank login form without showing any error messages

When I look at the epicor admin console i can see the logged in sessions.

I have tried recycling the app pool associated with the EWA website.
I have tried changing the credentials associated with the app pool

I have checked the usual windows event logs but can’t see any associated error messages

Has anyone else experienced this?

Have you tried different browsers?

Yes I have - Edge, Chrome, Firefox. All have the same behaviour. Also tried incognito mode in Chrome.

Hi, have you checked IIS logs. Have tried on the appserver itself

It never times out? I have the same issue right now. I deployed it and it just sits there at the login after entering credentials.

Eventually I get an error though.

In my case, after entering the credentials it goes straight to the blank login form again.

The IIS log doesnt show anything other than a successful POST, presumably when the credentials are sent.

I just tried old IE11 and got in!

I wonder if the problem might due the fact that our EWA https has a self-signed certificate

I thought I had tried that, but I’ll try it again.

EDIT: Nope, no luck.

there was another thread about epicor using ie.

I have now tried Chrome that is installed on the app server and it works. I am not connecting to ‘localhost’
