The issue I am facing:
When I come back to the Pi's web interface after a certain time, the login timed out. This is expected, and it drops me back to the login screen. However, it takes over 1,5 minutes where it just sits there redirecting repeatedly. I can see the loading icon in my browser animate, but nothing happens. After 1,5 minutes and 38 redirect attempts, it finally shows the login screen.
Details about my system:
Raspberry Pi 4b, 32-bit Raspian. Fully updated. Webserver log shows:

at one point I had top and htop open, it doesn't show anything out of the ordinary. No high load, no iowait, nothing seems to be locking up the system as far as I can see.
What I have changed since installing Pi-hole:
Too much to mention, but it generally runs smoothly, no issues. If there's anything specific you need to know, please ask and I will provide the details.
