I receive the following error since today in the morning (yesterday all was fine, no changes):
System.Data.SqlClient.SqlException (0x80131904): A connection was successfully established with the server, but then an error occurred during the login process. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.) ---&amp;amp;amp;gt; System.ComponentModel.Win32Exception (0x80004005): An existing connection was forcibly closed by the remote host
I saw some new firewall settings in the portal, that I have never seen before.
Deny public network access. I disabled this already (it was not set).
Can you help me?
