Please run pihole -d from the terminal of the Raspberry Pi and type y to allow the debug log to be uploaded. This will help us see what the current configuration is and prevent us from having to ask a lot of questions while troubleshooting your issue.
I did read a post that contained a very similar issue to the one I am experiencing and the poster had also followed the Crosstalk instruction.
If the error "no internet access with custom 127.0.0.1#5335" is the result of following the Crosstalk instructions, might one of my options be simply removing the whole of the install and starting afresh?
If the above is an option where would I find a reliable, simple, set of instructions to follow, I used the Crosstalk instructions as they were well presented on YouTube and also clearly written down.
It would be best to start with a fresh flash of the latest Raspberry OS using the Lite version of the distribution. https://www.raspberrypi.com/software/
I have tried to provide a Debug log but get this message
The debug log can be uploaded to tricorder.pi-hole.net for sharing with developers only.

I have turned off the Pihole as I don't understand what is happening as I have so many queries, see the insert and the bottom of this post, if I do have a loop, which maybe the case I don't know how to rectify it. I have a fresh install and do not want to change things and make the problem more complicated!!!
I have turned off my Routers redirection to the PIhole and have been able to generate a debug log, the token is 4eqSxEH7
I think the issue may not be helped by the strange way you have to have to allocate a Manual DNS in the GL.iNet GL-AX1800(Flint) router. This are not my settings but I have the Mode set to Manual DNA and in DNS Server 1 the fixed address of the pihole, DNS server 2 in blank, the two options are also selected on my router. There is a third setting on my router "DNS Rebinding Attack Protection" this is also selected.
One of the issues I'm having is I am unable to update gravity or upload a debug token I have searched for a solution however, the response I receive after running
sudo nano /etc/resolv.conf
Is different to the one in the solution
My response is
Search............................ lan
nameserver ...................(the IP address of my router )
I don't want to add to the problem by altering anything
