Mega created “S4 Buckets” compatible with s3 solutions, have simply managed to config it with Restic and other backups solutions, but I can’t manage it with AMP.
My Mega S3 configuration:
Endpoint: https://s3.eu-central-1.s4.mega.io
bucket (Example): minecraft
Key ID {MEGA_ACCESS_KEY}
ApplicationKey {MEGA_SECRET_KEY}
