Problem signing in using PGP key

[mikecobb-io]

My site has the following code in the home page:

<a href="/key.txt" rel="pgpkey authn">PGP Key</a>

key.txt contains my public key. However when I sign the challenge with the matching private key I get the following error:

There was a problem! The signature was valid, but was signed with a different key than we expected.

I'm not sure what I am doing wrong.

Maybe you can check if you had also encrypted? It's possible to encrypt and sign at the same time

Sorry, I'm having trouble getting things working with PGP keys so I'm just disabling it entirely for now.
