Posted March 28, 20205 yr Have seen frequent reminders that versions need to be the same. Firmware: Insteon_UD994 v.4.7.3 UI: Insteon_UD_994 v.4.7.5 Attempted automatic upgrade from 4.7.3 to 4.7.5 and received a message "Upgrade Failed :Failed uploading file (reported written size is invalid) This was followed by another error message "Socket Timeout Error". Firewall was off. Operator error?

March 30, 20205 yr Author Thank you for the response. I did have the firewall off and tried from two separate PCs with same result.
March 30, 20205 yr Author Made another attempt tonight and the upgrade was successful. Case closed. Thanks again.
