Update button does not work

Yesterday I updated my RP2 with OTA to version 2.224. According to the Volumio website there are already 2,245 for Raspberry. When I click on the update button, nothing happens.
Not even a popup will show that the version is up-to-date. I have not changed anything on the system.
