Error 403 or "Activation Error - Cannot connect to the Activation server!" when running activation tool a for web-activated license can be generated in a situation when the affected computer is behind a Proxy/Caching proxy or has proxy settings that are preventing direct access to CSI license activation server on ports 8080 and 8443.
| Info |
|---|
The license activation server ports are 8080 and 8443. If either of these ports is blocked, they need to be opened, otherwise license activation will not be possible. |
Troubleshooting
To troubleshoot the error, the users should check if they have any Proxy settings or a "caching proxy server" that they are using and/or the Firewall they are using if they are not using any proxy server. This will help to determine if this is a network issue or if this is a computer issue.
If users have a Socks proxy server, such as IBM WebSphere Application server setup as a proxy server, they should check it has been set to only allow access to SSL port 443.
