G’day Eric.
Is the strange looking mount point for GPG/JWT keys accurate?
gpg_volume:/share/Container/container-station-data/lib/docker/volumes/passbolt/passbolt_gpg_volume
jwt_volume:/share/Container/container-station-data/lib/docker/volumes/passbolt/passbolt_jwt_volume
Default should look like:
volumes:
- gpg_volume:/etc/passbolt/gpg
- jwt_volume:/etc/passbolt/jwt
The browser uses GPG for auth and the mobile app uses JWT for auth.
You can check in your browser at https://passbolt_instance/settings.json?api-version=v2
Look for:
"jwtAuthentication": { "version": "3.3.0", "enabled": true },
You can also run a status report to find out detailed info on the JWT folder

This other forum post is very similar to your issue:

Let em know how you go.
