Posting here to document my attempts to resolve this issue, hopefully it can help other users with a similar issue. Thanks to mods who have helped me get this far.
I have a fresh install of HA that I cannot access through the browser by any method. It is listed as a wired (LAN) connection in my router UI and responds to pings, but that is all. I have tried:
- 15-20 re-flashes
- several re-downloads of 32bit and 64 bit images
- several power supplies
- several SD cards
- several SD card readers
- wifi and LAN install attempts
- specifically allowing TCP traffic to port 8123 as per this guide
- disabling windows firewall altogether
Debugging using this guide yielded the following report:

Would appreciate some pointers from more experienced folks. I’ve had HA working in the past and it seemed great, but I’m not sure I want to automate my whole life on something that breaks on a fresh install…
