[Solved] CAPSMAN2 - failure message

I am using a rb2011uias-2hnd with the firmware 6.38rc52

I have installed capsman2 and a working configuration to manage the wlan. If I initialize Capsman2 again, the certifications I delete before, I can register the wlan1 problem-free at capsman2. It also works everything. This messages is in log:
capsman2_generate_error.PNG
When I restart the mikrotik I get the following error messages and the wlan does not work anymore:
capsman2_error.PNG
My Settings:

what am I doing wrong?

thx
Rosi

PS.:
I have flashed version 6.37.3 and then again the version 6.38rc52.
Now everything seems to work again. I do not know why, because I have changed nothing in the configuration.
