I modified the iRule (I think I just had to add "return" at the end, still same issue.

Yes, there are other iRules but this whitelisting iRule is first in order so I don't think it is even getting to the next one to cause issues.

I will see if I can open a case with F5 support.

Appreciate your efforts to check this, thank you!
