Problem creating new connection (REST)

[mall1m]

Dear All,

I'm trying to create a connection to a web service

With any webservice, "Test connection" is successful but when I try to "Create", it keeps sending an "access forbiden" message (see screenshot below)

I tried to check the log but didn't manage to find any file related to connection creation

I also tried to add RootAdmin security rules or create a new one with full access on DataConnection

Does anybody has an idea of what is wrong ... surely something obvious but I can't manage to find it

Thanks in advance

seems to be linked to server security

- Chrome is allowed on server and able to connect to internet

BUT

- IE is blocked and it's impossible to add trusted site

I guess that REST connector use IE to connect to URL
