Hello Andzej,
as I remember it was short after hard-reboot and subsequent log in, but I'm not sure.
Today I tried again two cases, hard- and soft-reboot, now with FW version 07.04.1.
I soft-rebooted the system, which took about 170 seconds. Almost simultaneously with the authorization dialog a message "Request timeout" occured.
I hard-rebooted the system, which took about 110 seconds. No error message occured.
I soft-rebooted the system, which again took about 170 seconds. No error message occured. But instead it took a long time until the Status > Overview screen was filled with data. Then it took again nearly about 60 seconds until the CPU load dropped from 100% down to about 27%.
Are there timing problems between the firmware serving for the WebUI and the part which performs board support?
What is the difference between re-installing via bootloader? It should justify the additional effort!
Thanks and BR
Guenther
