What a rollercoaster!

I have spent three hours trying to fix an internal error whereby my entire site was constantly redirecting. I have no idea how it came about, one minute it was working and then the next thing the entire thing went NOPE and stopped working.

I am spent after that. I am teaching myself how to use reverse proxies and this whole docker set-up is new to me so it's a steep learning curve!

What's the longest you've ever spent trying to fix an error that you have no idea how it came about?

Ouch! How did you fix it in the end? What was your thought pattern? If you can remember haha. I hardly remember how I got the site to stop this continuous redirection and it was only yesterday!
