On the client: Note that by default the WebAdmin page was called on port 22350 via HTTP: http://localhost:22350/index.html The current CodeMeter Runtime demands, that license and WebAdmin use separate ports, for which at least 2 ports are designated: 22352 (for HTTP) and 22353 (for HTTPS).
A) By default HTTP is enabled and the communication uses port 22352. If this does not work, check with your network administrator whether a HTTP connection is allowed.
B) Alternatively use a HTTPS connection for the WebAdmin, both with a self-signed certificate and with your own certificate. To use a self-signed certificate, it is sufficient to activate HTTPS in the registry. Please proceed as follows: 1) Stop the CmWebAdmin service via the Windows services. 2) Change the value under 'Enabled' under HKEY_LOCAL_MACHINE\SOFTWARE\WIBU-SYSTEMS\CodeMeter\Server\CurrentVersion\HTTPS from 0 to '1'. 3) Now restart the CmWebAdmin service via the Windows services.
