I've just added backups to AWS to a Virtualmin Pro instance, and am getting the (to me) cryptic message: -
HTTP/1.1 400 Invalid URI: isHexDigit
The target URI was simply cut and pasted from a working instance and the bucket name changed, and it is: -
...so I don't think that it is this URI that is referred to.
I'm a bit stumped as to ho to troubleshoot this, as backups normally "just work" - any clues?
