Hello Pi-hole Community! Grateful for any suggestions as to why my network or router config isn't working. Details below w/ my debug log. Thanks!

If you are Experiencing issues with a Pi-hole install that has non-standard elements (e.g you are using nginx instead of lighttpd, or there is some other aspect of your install that is customised) - please use the Community Help category.

Expected Behaviour:

Pi-hole is running okay on my Rasp Pi, but not on other devices. I had it running on all devices w/ my router configured correctly - but then I went on vacation, there was a power blip while I was away, and I lost my router config. My router is a TP Link Archer C7 (AC 1750) V2.

Actual Behaviour:

Only works on my Raspberry Pi and not other devices on my network

You are running a very old Pi-hole installation (almost 1 year) and missing a lot of fixes and security patches. Please update and post a new debug token.
