I have tried to do it using browsers, safari, mozila, chrome and edge, the same site status is not reachable and for firewalls on the client side and on the network side I have turned it off.

This issue has been successfully resolved by adding an ACL configuration, deny destination port 8905.

Thank you, everyone.
