Cause
Bamboo is loading an expired license key during startup. This error occurs when a customer has two licenses in their account, but the expired license is applied to Bamboo.
The property below in your <Bamboo_Home>/bamboo.cfg.xml
file contains the expired license:
1
<property name="license.string"> (valid license value here) </property>
Solution
Stop your Bamboo instance
Backup the
bamboo.cfg.xml
file somewhere else on your file systemLogin to MyAtlassian
Retrieve the valid license key
Copy and paste the new license key in the property below, overwriting the one that expired:
1
<property name="license.string"> (valid license value here) </property>
Restart your Bamboo instance
