Known problem caused by changes associated with the most recent hub firmware update. See the following thread:

Fibaro dimmer 2 not working (no response) (August 2019)

The dimmers are visible in the app as “off”, but not possible to use. When trying to dim or turn the light on, I get the pop-up “Server or network failure”. Happened while pairing devices. Anyone with similar experiences? Seems related to a firmware upgrade but have not received a confirmation from ST staff. Anyone with a solution? Even unpaired the dimmers and factory resettled the ST hub and paired all devices in again, but got same results
