What's Wrong?

API error is thrown:

  API Error (Connection error.) · Retrying in 4 seconds… (attempt 4/10)
    ⎿  Error (self signed certificate in certificate chain) (SELF_SIGNED_CERT_IN_CHAIN)
  ⎿  API Error (Connection error.) · Retrying in 10 seconds… (attempt 5/10)
    ⎿  Error (self signed certificate in certificate chain) (SELF_SIGNED_CERT_IN_CHAIN)
  ⎿  API Error (Connection error.) · Retrying in 16 seconds… (attempt 6/10)
    ⎿  Error (self signed certificate in certificate chain) (SELF_SIGNED_CERT_IN_CHAIN)
  ⎿  API Error (Connection error.) · Retrying in 32 seconds… (attempt 7/10)
    ⎿  Error (self signed certificate in certificate chain) (SELF_SIGNED_CERT_IN_CHAIN)
  ⎿  API Error (Connection error.) · Retrying in 32 seconds… (attempt 8/10)
    ⎿  Error (self signed certificate in certificate chain) (SELF_SIGNED_CERT_IN_CHAIN)
  ⎿  API Error (Connection error.) · Retrying in 40 seconds… (attempt 9/10)
    ⎿  Error (self signed certificate in certificate chain) (SELF_SIGNED_CERT_IN_CHAIN)

There were two other issues open related to this, but they were both closed with no apparent resolution: #2903 and #3374

The recommendation in the above issues is to turn off NODE_TLS_REJECT_UNAUTHORIZED, but that is not really acceptable, as it compromises security.

What Should Happen?

It should work out of the box without having to modify TLS settings.
