Hello…I came across this post and your answer because I just set up cloudflare tunnel and my Home Assistance is the only docker container I cant set up. I get a 400 Bad Request error when i set the tunnel as http. when i set it up as https i get 502 Bad Gateway error.
I read your solution but I am not sure how to implement it…I am new to self hosting so I am still learning what everything means and where to do. Would you mind directing me how and where to go and fix my problem? Thank you!
