2.2.0.1 CommandLine help googledrive gives 3 timeouts you can adjust:

  --short-timeout (Timespan): Short operation timeout
    The timeout in seconds for short operations like delete and create folder
    * default value: 30s
  --list-timeout (Timespan): List operation timeout
    The timeout in seconds for listing files and folders
    * default value: 10m
  --read-write-timeout (Timespan): Read/write operation timeout
    The timeout in seconds for read and write operations. If no activity is detected in this interval, a timeout error is raised
    * default value: 30s

I don’t think you’re in a list, so that cuts it to 2. You can raise one at a time.
Personally, I think these timeouts are too low, as TCP retry may exceed them.

Duplicati can retry, and here it had to do it a lot. Watch this value while tuning.
