Unable to sign images with error: metadata for targets expired

Hello,

We’ve been using DCT successfully for a few years until recently when all new image pushes fail with a message similar to the following:

08:06:43 time=“2022-10-28T09:06:43+01:00” level=error msg=“Metadata for targets expired”
08:06:43 time=“2022-10-28T09:06:43+01:00” level=error msg=“Metadata for targets expired”
08:06:43 Error: remote repository docker.io/organization/imagename out-of-date: targets expired at Thu Oct 6 16:42:48 BST 2022

I’ve tried adding a new signing key assuming it has expired for the repository, but I was unable to getting the same error. ( docker trust signer add --key .\key.pub signer organization/imagename )

Adding signer “signername” to organization/imagename…

Error: remote repository organization/imagename out-of-date: targets expired at Thu Oct 6 16:42:51 BST 2022

Failed to add signer to: organization/imagename

Any help would be appreciated.
Regards
