MikroTik Configuration Issue

Hi everyone,
I’m currently facing an issue with my MikroTik router, and I need some help troubleshooting it. Below are the details:
Router Model: MikroTik RB4011iGS+5HacQ2HnD
RouterOS Version: 7.10.2

# Example MikroTik Configuration
/interface ethernet
set [ find default-name=ether1 ] name="WAN" disabled=no
set [ find default-name=ether2 ] name="LAN" disabled=no
/ip address
add address=192.168.88.1/24 interface=LAN
/ip dhcp-server
add name="dhcp1" interface=LAN address-pool=dhcp_pool1 disabled=no
/ip firewall nat
add chain=srcnat action=masquerade out-interface=WAN

I’m experiencing connectivity issues where devices on the LAN cannot access the internet. I suspect there may be a problem with the NAT configuration or the DHCP server settings. Error messages: “Unable to reach the internet” on client devices.
I would greatly appreciate any guidance or suggestions on how to resolve this issue. Thank you in advance for your assistance!

This is not configuration, is just a part of it, make sure you have all configuration here and also some logs will be great!
