Error: Failed to Solve: Authorization Status: 401: authorization failed

Hello…

I’ve been trying to build and push docker buildx images using multiple platforms to DockerHub.

sudo docker buildx create --name mybuilder

After successfully creating a builder instance, I then began to run:

sudo docker buildx build --platform linux/amd64,linux/arm64 -t docker.io/xxx/test:test1 --push  .

I’m running into the issue…

I have successfully pushed am image using docker push . so I know nothing is wrong on the DockerHub side.

After researching this issue for the past few days, I’ve found a few answers online to fix this but nothing seems to work for me.

I’m currently using:

And Buildx:
github.com/docker/buildx v0.6.3-docker 266c0eac611d64fcc0c72d80206aa364e826758d

Also, I was able to successfully login to my dockerHub account using CLI. Wondering if anyone has any thoughts to fix this?

Btw… I’m using Ubuntu 20.04 Focal!

Thanks so much!
