An error has occurred during metrics gathering:

error collecting metric Desc{fqName: "snmp_error", help: "Error scraping target", constLabels: {}, variableLabels: []}: Error getting target : Request timeout (after 3 retries)

Temporary Fix

Adding other SNMP versions to the snmp.yml.

ubiquiti_airmax:
  version: 1 # <<<<
  walk:
  - 1.3.6.1.2.1.2
  - 1.3.6.1.2.1.31.1.1
  - 1.3.6.1.4.1.41112.1.4
# ....

ubiquiti_unifi:
  version: 1 # <<<<
  walk:
  - 1.3.6.1.2.1.2
  - 1.3.6.1.2.1.31.1.1
  - 1.3.6.1.4.1.41112.1.4
# ....

Now it is working fine.

AirOS only supports SNMP v1. But the Unifi systems support SNMP v2, if you are unable to use SNMP v2 with Unifi, you need to update your software settings.

Ok so only the AirOS is wrong.
