Hi everyone, I wanted to share my recent experience with resolving an issue I encountered with my Home Assistant (HA) installation. It’s been quite a journey, and I’m happy to share how I managed to fix it, in case anyone else runs into similar problems.A few weeks ago, I noticed that my HA setup was making some unusual DNS requests. I had set up HA on my Raspberry Pi 3B, using DietPi as the operating system. Everything was working smoothly until I decided to place HA behind a reverse proxy for better security and accessibility. That’s when the issue started to surface.The main problem was that after logging in to HA via my domain name, I kept encountering a ‘Retry’ prompt. This was frustrating, as I couldn’t access HA reliably. After some research, I discovered that my uBlock Origin extension was blocking certain requests, which was causing the login process to fail. Once I disabled uBlock Origin, the issue seemed to resolve temporarily. However, I was still concerned about why HA was sending requests to my DuckDNS hostname instead of my actual domain.I decided to dig deeper into the DNS configuration. I realized that the DNS record for my domain was set up as a CNAME pointing to my DuckDNS hostname. This setup was causing HA to redirect requests to the DuckDNS hostname, which was then being blocked by uBlock Origin. To fix this, I changed the DNS record to an A record pointing directly to my Raspberry Pi’s static IP address. This adjustment ensured that all requests went through my domain name without any redirection, effectively resolving the issue.Reflecting on this experience, I learned the importance of carefully configuring DNS settings, especially when using a reverse proxy. It’s crucial to ensure that all domain configurations point correctly to avoid unexpected behavior. Additionally, being mindful of browser extensions and their potential interference with network requests is something I’ll keep in mind for future troubleshooting.I’m grateful to the HA community for the wealth of resources and forums that helped me navigate this issue. It’s amazing how a supportive community can make such a difference in solving technical challenges. If anyone else is experiencing similar DNS or login issues, I encourage them to check their DNS configurations and browser extensions as potential culprits.Happy automating!
