Details about my system:
Can't use my phone or my laptop, i try clearing out catch & cookies both devices
What I have changed since installing Pi-hole:
I updated pi hole and still can't access it.
Before noticing i couldn't get to into Pi-hole dashboard was after updating firmware on my wifi router.
If anyone can please help me, I would appreciate it.
Try to access the Pi-hole via IP address instead of pi.hole, probably the devices do not use Pi-hole as DNS resolver currently (then pi.hole is not resolved) , which then would need to be investigated as well.
Think i find from my WiFi router,"192.168.50.126" and when i enter & apply back to the DNS. everything is working again. YAY!
thanks for your help BTW.
