Can't connect to admin page

[Chaoscore]

Hello!
Im kinda frustrated and starving for help.
I got a Pi Zero with Rasbian and Pi Hole v5 installed.

Im only able to access the admin page after windows logon for several minutes.

pi.hole or direct IP wont work. If i am lucky i can connect via putty and SSH.

i did a quick pihole -d.

these are the erros:

i already pihole -r and did a complete reset this way.

The weird thing is that suddenly after some minutes the admin page cant be accessed.

Mostly if i am able to connect at the beginning it is via pi.hole.

I apreciate any help and i did most of the stuff ppl where toled in other threads!

httptdp restarted mutliple times etc.

sry for my poor english!
much love.

Your screenshots indicate some problems with IPv6 connectivity.

Those could only and only partially explain why access to Pi-hole's UI via hostname fails for you if your client would prefer IPv6 over IPv4.

Access via Pi-hole's IPv4 address should always work, given IPv4 connectivity of your Pi-hole machine.

We'd get a more complete picture if you would actually upload the Debug Log. This can be done via pihole -d, and it will be sufficient to post the token here as shown at the end of the upload.

Hope this helps :()

Your debug log looks normal with regard to Pi-hole's web interface, showing lighttpd has been chosen on installation and is listening and properly answering requests:

*** [ DIAGNOSING ]: Setup variables
    INSTALL_WEB_SERVER=true
    INSTALL_WEB_INTERFACE=true
    LIGHTTPD_ENABLED=true

*** [ DIAGNOSING ]: Ports in use
[80] is in use by lighttpd
[80] is in use by lighttpd

*** [ DIAGNOSING ]: Dashboard and block page
[✓] Block page X-Header: X-Pi-hole: A black hole for Internet advertisements.
[✓] Web interface X-Header: X-Pi-hole: The Pi-hole Web interface is working!

However, it seems like you've recently changed your configuration with regards to IPv6, as your Pi-hole shows blocking, but only zero requests in stats, and your previous screenshots show an IPv6 ULA address in use, where your debug log now shows only a global address.
Note that a ULA would be preferred, as Pi-hole needs a stable address, while a global IPv6 may change over time for various reasons (see also Use IPv6 ULA addresses for Pi-hole).

That limits the problem to your PC, making it very unlikely that this is a Pi-hole issue.

Check if something on that machine blocks access to Pi-hole.
Your browser may mistakenly restrict access to Pi-hole if you are using ad-blocking extensions, or some anti-virus DNS feature may interfere. Still, this could only explain why your Pi-hole isn't accessible by its hostname.

And unless a local firewall on your PC blocks Pi-hole's IP, access by IP should always work, the only exemption being use of a link-local IPv6 address (fe80::) when Pi-hole and your PC would reside in different network segments (which would be uncommon, but not impossible in a home network).

My Windows 10 seems to block it somehow. A fresh install fixed it.

thank you very much for checking my logs (:

kudos for the help.
