Consul member Failed to join but doesn't exist

Consul

Hi,

sorry I’m new with consul so excuse my stupid question but struggling to find the answer on the net…

I run a small consul network. All servers we launch have the following command with different ip addresses:
C:\consul\consul.exe agent -server -client "10.19.50.207 127.0.0.1" -bind=10.19.50.207 -data-dir=C:\consul\data -config-dir=c:\consul\config -dns-port=58600 -http-port=58500 -grpc-port=58400 -serf-lan-port=58301 -serf-wan-port=58302 -server-port=58300 -enable-script-checks=true -log-file=C:\consul\logs\consul.log -log-rotate-bytes=10000000 -log-rotate-max-files=10

my consul.json is like:

{
	"datacenter": "hk-jade-prod",
	"log_level": "DEBUG",
	"ui": true,
	"client_addr": "10.19.50.207 127.0.0.1",
	"bootstrap_expect": 6,
	"retry_join": [
		"10.19.82.245",
		"10.19.83.13",
		"10.19.82.9",
		"10.19.82.146",
		"100.81.34.136",
		"100.81.17.233"]
}

In the logs I will get errors like below on members that are not even alive anymore:

2021/07/08 18:53:38 [WARN] agent: (LAN) couldn’t join: 0 Err: 6 errors occurred:

So I’m confused.
When I list the members I can see jade-net-master. But I don’t know what it is and it is associated with ip 127.0.0.1:58301

cyril-jade-net-master was also associated with that ip but I killed it with a force-leave -prune command. Now it’s gone but error still popup.

Any advice about what I’m doing wrong?
