Hey node, welcome to the forum!
Using google drive for storj is a really bad idea. This will add a lot of additional latency and will really mess with the workings of your node.
The idea of storj is to store data decentralized. If nodes are going to store it on another cloud somewhere, they would also be reintroducing a single point of failure. In short, you should really not be using google drive at all.
However, the debugging steps are the same no matter what you use. Have a look at your docker logs to see if something relevant is mentioned there. docker logs --tail 100 storagenode
