Hi Cody, this likely happens because Slice Machine is trying to access localhost over HTTPS (note the :443 in the errors).
localhost` typically is not accessible over HTTPS unless you have a local certificate set up.
If you do not have a certificate set up, could you confirm your slicemachine.config.js file does not contain https:// under the localSliceSimulatorURL property? It should be http:// instead (no s).
have you noticed that the log gets displayed at a certain time? Or right when you launch SliceMachine? Are you connected to Prismic via SM? Can you properly login? Also, do you happen to use a fire vault?
It happens every time I navigate around in SM.
I did logged in to Primic via SM. Like I said, everything run normally except for the error log.
I don't know what a fire vault is.
