We are trying to configure a sharepoint online client.
We installed the sharepoint client on the proxy (Commserve will serve as proxy).
When we try to add the office365 client we get the error "Browse request failed".
.NET 4.6 and powershell 5.1 are installed, user is tenant admin and tenant site looks right.
At the network level we can telnet tenant site.
Does any have an idea what can be the problem?
