400 Bad Request - The plain HTTP request was sent to HTTPS port

[lorddaedra]

I followed this guide https://developers.cloudflare.com/argo-tunnel/reference/kubernetes/

But in my case I prefer to use http2 for performance (https://imagekit.io/demo/http2-vs-http1) and security (mitm) reasons...

I see error 400 Bad Request - The plain HTTP request was sent to HTTPS port

I use Cloudflare Origin Certificates for my services...

Also I enable Automatic HTTPS Rewrites in Cloudflare panel.

I do not expect to see any plain http requests here... How to fix it?..

Hi @lorddaedra , could you solve your problem? The same thing is happening to me, any idea how to solve it?
Thanks

I've also run into this issue - anyone found a reason why or how to solve it?

[lorddaedra]

@skilledboy I am sorry to have kept you waiting for so long.

@ here
I do not use cloudflare-ingress-controller anymore. (I use Google Cloud Run service for most of my projects...)

[skilledboy]

thanks @lorddaedra , I am particularly a fan of Google Cloud Run, but unfortunately it is not useful for me to expose my services from my raspberry pi 4 cluster. For this reason I use https://developers.cloudflare.com/argo-tunnel/reference/kubernetes

I leave you an image of how I mix everything (Cloudflare argo tunnel, kong gateway, etc ...).

Sorry, my english is very bad

We are currently more focused on improving the cloudflared client itself, leaving this ingress controller deprecated. You can read more here: #172 (comment)
