Trouble connecting to additional nodes when creating HA Rancher cluster

Archive Rancher 1.x
1

I am trying to set up a Rancher HA cluster. For this purpose i set up a MySQL server on an ubuntu core 16.04 and have set it up as follows using the Rancher documentation.

CREATE DATABASE IF NOT EXISTS cattle COLLATE = 'utf8_general_ci' CHARACTER SET = 'utf8';
GRANT ALL ON cattle.* TO 'cattle'@'%' IDENTIFIED BY 'SomePassword123-';
GRANT ALL ON cattle.* TO 'cattle'@'localhost' IDENTIFIED BY 'SomePassword123-';

I have then on my first docker node started the first instance of Rancher.

sudo docker run -d --restart=unless-stopped -p 8081:8080 -p 9345:9345 rancher/server --db-host 192.168.1.145 --db-port 3306 --db-user cattle --db-pass SomePassword123- --db-name cattle --advertise-address 192.168.1.77 --advertise-http-port 8081

And on the second docker node.

sudo docker run -d --restart=unless-stopped -p 8081:8080 -p 9345:9345 rancher/server --db-host 192.168.1.145 --db-port 3306 --db-user cattle --db-pass SomePassword123- --db-name cattle --advertise-address 192.168.1.78 --advertise-http-port 8081

Now, i can access the first instance just fine, and if i go under Admin–>High Availability, i can see the second node.
But i can not access the second node on its HTTP port 192.168.1.78:8081

If i look in the logs for the first node i see this when i try running a second one.

On the secondary node(s) i get this error repeated.

Can anyone point me in the right direction. I feel like i followed the official guide very closely.

I didn’t fix the problem yet but i got some info. Im running my servers on an esxi cluster controlled by a vcenter server locally. It’s my testing environment. When i tried running the rancher containers on a server in the live environment it worked fine. So perhaps it’s a problem with multicast on my testing environments network?

I am running an HA Rancher cluster on ESXI (managed by vCenter) and it works for me. I am using the default port of 8080, so maybe try using the default port and see if that works.
