Server selection timed out mongo DB configuring master Tenant

[davidcas9]

I get this message when selecting the existing configuration upon running node install in the top level directory:

Now setting configuration items.
Now configuring the master tenant. 

error [24 Jan 21 14:33:51 -05:00] Server selection timed out after 30000 ms
error [24 Jan 21 14:33:51 -05:00] failed to set app.db

I think this is an issue with mongo? https://github.com/Automattic/mongoose/issues/8381

I had the same issue. My localhost was resolving to ::1 (ipv6) and mongo was only listening on 127.0.0.1. Changing localhost to 127.0.0.1 resolved my issue.

Change config file dbhost field to 127.0.0.1
