The Update Center information is actually downloaded but the previous information is cached, so the obtained data is not the latest one.
To invalidate such cache and make the updated data to be retrieved, the following Groovy script can be used through the Script console:
Jenkins.get().getUpdateCenter().doInvalidateData()
