Number Effect/cause Remedy
230202 WININET.DLL has detected an error. This error
usually occurs when it is not possible to make a
connection to the server or the server rejects the
attempt to make a connection because the client
lacks the authorization.
An unknown server certificate can also be the
cause when the connection is encoded through
SSL.
The text of the error message provides more
information.
This text is always in the language of the Windows
installation since it originates from Windows.
Process values are no longer exchanged.
Depending on the cause:
When a connection cannot be made or a timeout occurs:
•
Check the network connection and the network.
•
Check the server address.
•
Check if the web server is actually running on the
target computer.
In the absence of an authorization:
•
Configured user name and/or password do not match
those on the server. Match them.
When the server certificate is rejected:
Certificate signed by an unknown CA ( ):
•
Either set the configuration to ignore this point, or
•
Install a certificate that has been signed with a root
certificate known to the client computer.
If the date of the certificate is invalid:
•
Either set the configuration to ignore this point, or
•
Install a certificate with a valid date on the server.
If there is an invalid CN (Common Name or Computer
Name):
•
Either set the configuration to ignore this point, or
•
Install a certificate with a name that corresponds to
that of the server address.
230203 Although a connection can be made to the server,
the HTTP server rejects the connection because
•
WinCC flexible Runtime is not running on the
server, or
•
The HTTP channel is not supported (503
Service unavailable).
Other errors may occur if the web server does not
support the HTTP channel. The language of the
error text depends on the web server.
Data is not exchanged.
For error 503 Service unavailable: Check if:
WinCC flexible Runtime is running on a server.
The HTTP channel is supported.
230301 An internal error has occurred. An English text
explains the error somewhat more specific. One
possible cause is insufficient memory, for example.
