Generic SNMP Error?

Configuration
1

My SNMP sensors are not working but the config validates. However when I restart Home Assistant I get this in the logs and the sensors don’t work:

2019-01-06 00:16:14 ERROR (MainThread) [homeassistant.components.sensor.snmp] Please check the details in the configuration file

The config isn’t anything special. And as mentioned above it validates when checking it:

Any thoughts?

This is my config and it works try adding the version I seem to remember that caused me some problems but it was a long time ago.
- platform: snmp
version: 2c
scan_interval: 120
accept_errors: true
name: “Router WAN 1 RX”
host: 192.168.0.1
port: 161
community: !secret snmp_read
baseoid: 1.3.6.1.2.1.31.1.1.1.6.5
unit_of_measurement: ‘GB’
value_template: ‘{{((value | int) / 1000000000) | round(2)}}’

Still doesn’t work. Also tried the “accept_errors: true” config but then everything shows as unknown:

2019-01-06%2011_39_58-Home%20Assistant
2019-01-06%2011_39_58-Home%20Assistant1206×359 44.4 KB

I feel like I’m missing something really dumb…

So using a CLI sensor works around the issue…I guess:
