I am running a few S3-compatible (Minio) backups now and encountered the following problem when setting up a new one:
I was creating the backup and had selected (I think) S3-compatible. I entered Access and Secret and tested the connection. It worked but (as it should) complain about the SSL (self-signed). I added the hash to accept-specified-ssl-hash and tried again. I got the error message “Failed to connect: The request signature we calculated does not match the signature you provided. Check your key and signing method.”. Now, whatever I do, I get this warning. Sometimes I can get the has complaint back, but I never get beyond that stage. This is on another machine than I am typing on now. But looking at the log, I get “The remote server returned an error: (403) Forbidden”. So, it seems the problem is somewhere on the backend and not Duplicati, but I am having trouble understanding this because so far it seems other than credentials and target the setup that works is identical to the one that doesn’t.
So, I thought to remove this configuration entirely and I tried to, but the configuration won’t go away. Any tips I can look into?
