I have around 10 installations of duplicati running some of them are running on old versions, using Google drive which are working fine, i am still scratching my head ?? is it google drive issue or duplicati issue

I looked for previous forum work for similar issues. The ones that were successful generally had enough stack trace to see a particular storage provider, and a means to fix. The stacks here don’t go far enough. Setting up a –log-file could catch more, or if emailing errors, then perhaps raise this option above default:

C:\ProgramData\Duplicati\duplicati-2.0.4.5_beta_2018-11-28>Duplicati.CommandLine.exe help send-mail-max-log-lines
  --send-mail-max-log-lines (Integer): Limits log lines
    Use this option to set the maximum number of log lines to include in the
    report. Zero or negative values means unlimited.
    * default value: 100
