Thank god we now know what is causing the problem and you know how to work around it.
Probably your router reboot connects to a different vpn host and for a short time, cloudfare does not see the new ip address as a potential ddos attack so doesnt generate captchas. After a time persistent use of the same ip address provokes cloudfare to generate captcha codes.
At least my code debugging skills which I have not used for 20 years have been refreshed.
