Invalid certificate when pulling docker images

[saku]

Hi
I have upgraded the docker application on my F4-210 (Server Version: 20.10.17) but still unable to pull any images from docker. I am able to pull from GCR. Below is the error received consistently
error pulling image configuration: download failed after attempts=6: x509: certificate signed by unknown authority

Would appreciate a resolution for this issue.

Thanks

Please try other images to see if all images cannot be pulled successfully. This may only exist in individual images.

It is the same error for all images from docker while able to pull images successfully from GCR. Tried adding the CA certificates to /etc/ssl/certs and /etc/docker/certs.d folders but the same issue "x509: certificate signed by unknown authority" persists.

I am having the same issue with version 20.10.20 Docker pulls all fail. I can see "x509: certificate signed by unknown authority" errors if I do it from the terminal. In addition, the registry window in the gui is empty.

I'm having the x509 certificate issue as well.

Hello! Could you please tell us the version number of your TOS and the relevant applications? If you are not using the latest version, it is recommended that you upgrade them to the latest version first, so that we can troubleshoot problems for you more accurately or provide more suitable services.

I'm on TOS 4.2.40 in a f4-220. It says I'm updated to the latest version if I try to update. Docker is version 20.10.17. In Docker, in the gui the repository is empty and if I command line try to pull an image I get the x509 error.

Same x509 error here, TOS 4.2.41, latest one, F2-210. Docker has been broken on my NAS for a while now. It's very problematic.

Same issue here, f4-210

Hello. Judging by the message, the problem is of a general nature. Tell me if there is movement on this issue? My device: f2-210. TOS: 4.2.44. The problem is similar
