I get this problem too, and gpg doesn't list the key as expired. What can I do to help debug the issue?

[tomholub]

Please paste the key into FlowCrypt settings - additional settings - experimental - OpenPGP compatibility, and share the result

I see now that even though gpg lets me encrypt stuff, it does give an error when checking the key:

In case the problem lies with the key, it would be very appreciated if you told me what could I suggest his owner to do.

Thanks a lot.
