TCP access denied by ACL

I am using Cisco ASDM 7.3 for ASA on our network and am getting the following errors. I am a novice to Cisco firewall so any help would truly be appreciated. Thanks in advance. Here is the error:

 

TCP access denied by ACL from 151.74.189.169/32758 to outside:63.147.191.66/23

Re: TCP access denied by ACL

There is an access-list blocking the traffic. Try to identify it.

Re: TCP access denied by ACL

Hi,

It seems you don't have a permit for telnet (port 23) to 63.147.191.66 traffic in your ACL. You have and permit ICMP any, permit for IP .67, .69, .70, and deny for all else.

Re: TCP access denied by ACL

Is there any ASDM roadmap for identifying ACE number instead of generic ACL (deny) ?
