Have you got any idea for this situation?
I set up the DOS profile in block, and set the Device ID parameter in TPS and Stress Based Detection.
This parameter generated two interesting problem.
First, It cause a whitescreen for 10-30 sec before the user gets the site page.
Second, If someone would like to use my site with mobile, It randomly block some device, without any feed back, because the captcha do not work on android or iOS device.
I used QR code identification, it is problem?
If I switched off the parameter, these problem solved.
Thank you for your answer!
What dose it mean "very fine tuning" in this situation?
Beacuse as I know the dos profile can not learning from the traffic, how can i fine tune it?
