EmployeeThe best thing you can do is raise a case with F5 Support.
However, you should take a look at https://my.f5.com/manage/s/article/K9812 and turn on rst logging or cpaturing in a PCAP. My own thinking is that there is something on that virtual server which ASM doesn't like, so do a tcpdump for a single user and work out from there which request is causing the RST. A good idea would be to look at the webchat -

NimbostratusWhether the ASM policy is in Transparent mode or Blocking, when applied to Virtual Server, the connection is reset. The packet captures shows:
Internal error (ASM requested abort (plugin abort error))]
tmm1[29648]: 01230140:3: RST sent from *.*.*.*:443 to *.*.*.*:51570, Internal error (ASM requested abort (plugin abort error))
However, when I remove the ASM policy from the VS , the service works fine.
