Please, provide your public IP from this link

thank you for your answer sir, i'm really desperate i don't know what else to do:
Your Public IPv4 is:
Your IPv6 is: Not Detected
Your Local IP is:
Location: Bejucal, 16 CU
Your IP address is not included in the ban list.

Try to use another computer or internet provider, check the firewall settings.
I already tested on several laptops, without active firewall, and in Cuba there is only one internet provider, reinstall the samsung tool software, nothing sr
Try flashing a newer firmware such as G530TUVS2AQE3
