I’ve been looking at the Mongoose code that generated the error, in:
…node_modules\mongoose\node_modules\mongodb\lib\cmap
I’m not experienced enough to know what is fully going on, but it appears the connection is closing (line before is if (issue.isClose) {). The IP address in the error message (34.71.95.215) appears to be the Google Data Center where my VM is running. I’m not sure what this means by thought it my help for anyone who has ideas on next steps for me.
