Restore: Invalid password or corrupted data AND missing file

Do you have localhost:8200 still there? You want to remove whatever one you use, or test with your Edge.

If you suspect bad files, you can download it and decrypt with AES Crypt or Duplicati SharpAESCrypt.exe.

That should download most files. Another heavy download to test all files is The TEST command for all.
Commandline can do that, but you have to change the command yourself and type all in the arguments.

For best restore testing, use no-local-blocks=true to force Duplicati to obtain all data blocks from remote.

If any of your destination has direct access from Windows or Linux, you could also set upload-verification-file then run one of the DuplicatiVerify scripts in its utility-scripts folder which will check file hashes directly.
