Gaiad sync issue

[rocky2015aaa]

Summary of Bug

I have two issues.

1. When I follow gaia tutorials, I get these kinds of errors several times but syncing works.
   9:18AM ERR dialing failed (attempts: 1): dial tcp 162.55.132.230:2010: connect: connection refused
9:18AM ERR dialing failed (attempts: 1): dial tcp 106.12.73.242:26656: i/o timeout

2. According to quick start on document, At the 6910000 block height with panic, I need to change gaiad version.
   I want to test it but for syncing I want to use quick sync.
   https://cosmos.quicksync.io/
   If I use quick sync, running v5.0.5 is enough? No need to run from v4.2.1 and change gaiad version?

Version

gaiad version -> v4.2.1

Steps to Reproduce

On macOS Big Sur v11.5.2

quick start

this is normal, if you wait a period of time they will pass and you will have a peer. Tendermint spits out a lot of noise, but they are benign

if you are using quick sync then you only need to use the latest binary since you already have all the old state.
