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

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

Hi Mohammed, thank you for your reply. How do I identify access-lists? I appreciate your help.

Here are my current access lists: https://gyazo.com/eb57009f0909c563d9eba6470bc7e8cf

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.

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

If it doesn't specifically mention the ACL that is dropping this then it will be your commands to allow management connection to your ASA.

For example

ssh x.x.x.x 255.255.255.0 management

Obviously yours will be telnet specific.
