ESP8266 to Influxdb

I’m using an ESP8266 library (link) to write to Influxdb which is on my local computer. I’ve been using this to save my sensor data with no issues but I started to get this error since a couple of days ago. Any idea what’s causing this?

This error doesn’t really contain enough information to start troubleshooting, but my first guess would be some kind of network issue. Maybe an IP address changed? How do you test connectivity between the ESP8266 and the rest of the network? Is there a way to get more detailed error information from the library? Do you see anything in the InfluxDB logs?
