Emails encrypted with Addy.io cannot be decrypted by open-keychain

[xyhhx]

I'm running addy.io in a Docker container, version 1.0.4.

When I try to decrypt emails sent through addy.io using open-keychain, it fails.

I tried to encrypt a test text file from within the docker container, and decrypt that, it also fails.

If I export that secret key and use it on another machine to encrypt a text file, I can successfully decrypt that.

While the versions are slightly different, the configurations are otherwise the same.

If there's anything I can do to help with troubleshooting, please let me know...

When you say it fails, in what way does it fail, what error is shown?

Can you provide an example of the encrypted data that fails to be decrypted?

I am experiencing the same issue with both Thunderbird Desktop and Android. It used to work but suddenly I was unable to decrypt emails. I got a "unable to decrypt content" error. Surprisingly enough if one tried to decrypt them manually with the sequoia-pgp implementation, it worked fine.

I sadly do not recall the specifics of the GPG error shown both in the terminal and in Thunderbird, but afar it was related to the package version or something.

In Thunderbird Desktop I managed to fix the problem by changin my external gpg binary to sequoia-chameleon-gnupg(which is an improvement anyway) but I didn't have the same luck with Thunderbird Android + OpenKeychain.

P.D: Thunderbird shows this in all addy received emails:
