Pihole only works for wireless connection from specific network (acess point)

Sorry for not providing enough information about my network configuration, thanks for reviewing my log, nonetheless.

I tried with the following https://discourse.pi-hole.net/t/raspap-pihole/14739/7?u=jordeec but obviously it didn't work for me. I am also using raspap in combination with pihole.

Could you please point me out to a suitable tutorial or link in which I could review all the concepts you mention?
