I have a Claims-Based web application with a site collection.
I can not open the site from IE (neither from SharePoint Designer, it prompts for credentials) but it works fine from Chrome.
What can be the problem?
Sounds like it may be something simple, try entering fully qualified credentials for example domain\username
Can you confirm if its not the LoopBackCheck issue?
Please check this link, it may help you to fix that.
Alright. Probably you have saved credentials in your browser. Can you please try this?
The problem was the Claims Authentication Type, it was setted to Kerberos.
I changed it (for the default zone) to NTLM and it works fine.
