Big-IP ASM automatically removes my hostname

, but I don't see the violation reaching the threshold of 100.
Hello everyone,

Recently, my service has encountered an issue. In the evening, while everything was running normally, I received a block warning from ASM. Upon checking, I found that my hostname was automatically removed from the policy by ASM. I am using fully automatic as per this link: https://my.f5.com/manage/s/article/K000134503. However, the problem is that when I checked for violations, I did not see any violations related to violations="Illegal host name." So, why did it reach the threshold of 100 and remove my hostname? Could this be a bug? I checked that there were no accept suggestions at that time, only violations="Illegal repeated parameter name," which I do not think is the issue. Thank you.
