"invalid character '<' looking for beginning of value"

Hello,

First I want to say this is a very cool and interesting app, I love the statistics output feature. Recently, however, my deployment started giving me the following errors:

W0329 14:54:20.989396       1 metrics.go:128] Failed to obatin the geohash of 114.204.218.154: invalid character '<' looking for beginning of value.

This came seemingly out of nowhere as the pod was working just fine when I went to bed last night, but I woke up to these errors. There isn't an error before the pod switches from successfully geohashing to these errors.

Below is my deployment.yaml file for K8s:
