Sonoff 4 CH Pro - firmware update 3.7.3 to 3.7.6

Hello, i have a Sonoff 4CH Pro with a firmware 3.7.3
My app says there is a firmware upgrade, i have tried several times but everytime the firmware update fails and the wifi led is in blinking mode, i have to reboot the sonoff after failure upgrade to get it back online. (Reboot with power off and on). What could be the problem and how can i troubleshoot this problem? i do not find any logs that may help me.

Kind regards.

I had same problem. After several trials I figured the Wi-Fi signal was weak at that part o the house. The solution was to allow another closest mesh booster to be found and connected

hello, thank you for your reply. The problem has since been solved, an adjustment to my firewall was necessary to get that update done. Kind regards
