Legitimate traffic being blocked - R80.20

[Rafael_Lima1]

After migration to R80.20 we are having a legitimate traffic being blocked, filtering via "fw ctl zdebug drop", we receive the following log:

@;2731325746;[cpu_9];[fw4_2];fw_log_drop_ex: Packet proto=6 x.x.x.x:45242 -> y.y.y.y:443 dropped by fwmultik_process_f2p_cookie_inner Reason: PSL Drop: internal - reject enabled

We opened a SR and passed us the SK33328, which was done but did not work, we still have connection problems sometimes.

The traffic is from an apache server to an nginx, TCP / 443

Anyone else went through this and could help?

TAC recommended to install take 237.

Before that , they asked me the clear the url cache and restart RAD services. I will update once I follow these procedures.
