Failed to push images after building them

[hezhizhen]

I'm using buildkitd (v0.12.0) on the host and run buildctl (v0.12.1) commands to build images and push them to the private registry. Sometimes it fails and the logs are as follows:

Any advice will be appreciated.

It's quite like #3809 , but I suppose there's some slight difference in our cases.

Can you test with #4210 ?

Okay. I'll try it later.
