I installed PI-hole on the same machine that I expect to use Pi-hole for DNS, my linux PC (Debian 11, Bulleye) and I used "method 2" for installation (and config my router). Its work fine but after reboot my PC it doesnt work anymore. I tried to go to http: //pi.hole/admin but it won't let me.
Your Pi-hole debug log is normal and in the past 24 hours it has received the following DNS traffic:
[2021-09-14 23:26:25.154 1155M] Imported 6663 queries from the long-term database

If the Linux PC is not using Pi-hole for DNS, then it won't be able to reach http://pi.hole/admin, since only Pi-hole can resolve this domain name to the IP of the Pi-hole.
From the terminal on the Linux PC, what are the outputs of the following:
nslookup pi.hole
cat /etc/resolv.conf
Unrelated to this issue: these do not appear to be valid adlist URLs but they both appear in your adlists.
You're right, Pi-Hole works. The reason I did the post was because I was testing on Chrome at the time of posting. My default browser is Firefox and in this browser Pi-Hole works fine. Now when I open another browser, like Chrome, Pi-Hole doesn't work. I did the test by opening different pages and the ads appear in Chrome and not in Firefox.
There are two problems that I am noticing:
If I cannot enter the Pi-Hole page using the IP assigned to me, how do I add web addresses to the block list?
Every time I want to open a page it takes 3 or 4 seconds for it to open (using any browser).
