Client side checks such as antivirus, firewall, process, file, and so on, on CentOS 7 do not work. Server logs show "Access encountered error: ERR_ARG" for these clients.
Clients from CentOS 7 are not able to connect to BIG-IP APM.
This happens when client-side checks are configured on the BIG-IP system and CentOS 7 and Firefox client connecting to this BIG-IP shows symptoms
There is no workaround at this time.
