Solved I have faced same problem steps I did before starting fetching data

1. $zk = new ZKTeco('device ip', 'device port');
2. $zk->connect();
3. $zk->enableDevice()
4. $zk->getUser()

NB: if not working just refresh the page

I have been trying to use ZKLIB. But it wasn't consistent and efficient when I was trying(it may be my fault) then I switched to Python and start using pyzk and you can find docs here @akatech100

Thank you.

In my case was a blocked port UDP/4370 ... had access to TCP/80 (HTTP) but some firewall denied the UDP connection, once enabled the issue gone

Best regards
