Can not get attendance with running apache2 on Ubuntu

[huytq397901]

hi all, sorry for digging, I tried the configuration on php 7.3 vs apache2 (ubuntun 20.04) but could not get the log - attendance, while the same code php when running on xamp (run with Windows 10) got the log. How can i fix on Ubuntu. Tks

Did you check the firewall settings for the port you are using to connect to your attendance device?
