file and print sharing resource is online but isn't responding to connection attempts

Hello Experts,

I am facing issue with File Share over internet. I have a Server 2016 instance in AWS and I created few Shared Folders on that Server.

I am able to access those Shared Folder over public IP <\\Public IP\Share> from Server 2016 hosted in AWS, Azure, Google Cloud but unable to access the Shared Folder from Windows 10. I have enclosed the Windows Diagnostics Log here.

While troubleshooting the issue, I tried below steps but no luck. Please advice...

Allowed all traffics in AWS Security Group

Disabled Windows Firewall on Windows 2016 as well as Windows 10

Enabled SMB 1.0/CIFS Client on Windows 10

Tried to Telnet on port 445 but it was a failure

Disabled StrictNameChecking and SMB2Protocol on Server 2016. I used below commands:

Set-SmbServerConfiguration –EnableStrictNameChecking $False

Set-SmbServerConfiguration –EnableSMB2Protocol $False
