GTCJ Posted March 28, 2020 Posted March 28, 2020 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?
Michel Kohanim Posted March 29, 2020 Posted March 29, 2020 @GTCJ, Most probably firewall related: https://wiki.universal-devices.com/index.php?title=Configure_Firewall_Software With kind regards, Michel
GTCJ Posted March 30, 2020 Author Posted March 30, 2020 Thank you for the response. I did have the firewall off and tried from two separate PCs with same result.
GTCJ Posted March 30, 2020 Author Posted March 30, 2020 Made another attempt tonight and the upgrade was successful. Case closed. Thanks again.
