An Internet connection is required during the license validation process:
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
