Not able to connect to InfluxDB instance running on ubuntu 18.04 through local network

Hi,
I have 2 machines in local network and both have influxDB 1.8.6 installed. I am able to connect to influx db instance remotely on one machine but on another machine only able to connect locally.

Machine 1 - everything working fine
OS: ubuntu 20.04
Influx: 1.8.6

Machine 2 - influx working locally but not able to connect from other local IPs
OS: ubuntu 18.04
Influx: 1.8.6

testing:

- On machine 2: influx -host -port 8086 - connection works
- On machine 1: influx -host -port 8086 - connection doesnt work works

> - _`Failed to connect to http://192.168.1.229:8086: Get http://192.168.1.229:8086/ping: dial tcp 192.168.1.229:8086: connect: connection timed out Please check your connection settings and ensure 'influxd' is running.`_

- On machine 2: influx (everything works)
Update:

looks like issue is specific to ubuntu 18.04

Installed influx on another 20.04 machine and i can access it from outside

Start by reproducing the reported connection behavior with InfluxDB 1.8.6 on Ubuntu 18.04 and Ubuntu 20.04, using the local-network commands and addresses from the issue. Inspect the network and service configuration on machine 2; done when the cause of the remote timeout is identified and remote access works or the limitation is documented.
