An Internet connection is required during the license validation process:
If you have access to Internet via the Web application, the token will be validated automatically.
If you do not have access to Internet, you will need to click either the Generate validation request button, or the Validate your license manually button.
This behavior only occurs in commercial editions of Talend Products.
In Talend Administration Center, a message is displayed:
"License token will expire in xx days"
Depending on the version of Talend Administration Center you are using, you will need to validate the license token using:
Either the "Validate your license manually" button
or the "generate Validation request" button
A popup with the link (underlined and named link) will be displayed.
If you do not have an Internet connection, this link opens a browser with a token (e.g. j9d87sh9f32ush3d5fu). The browser displays an error message (no internet) but you can copy the link in the address bar and:
Copy the link into a text document
Go to a computer connected to the internet
Paste the link in a browser
Retrieve the token (such as j9d87sh9f32ush3d5fu)
Go back to the Web application and paste the token into the previous popup window
Click Enter validation token
In the Talend Administration Center User Guide, you can find additional information about license management
