[Solved]Error: Connection Error 595: Connection refused

ygolonac · Jan 22, 2014

Hello, I installed a cluster with two nodes (Prox1 and Prox2) in unicast mode.

when I access the gui of Prox1 I can not see or install anything on node 2 and vice versa equal, if I access next2 I can not do anything in prox 1. Tells me:

Error: Connection Error 595: Connection refused

thank you very much

Re: Error: Connection Error 595: Connection refused

Hi,
are both nodes in the GUI "green", or only the one where you logged in?

Any output in the logfile?

Re: Error: Connection Error 595: Connection refused

what is the output of:

# cat /etc/pve/.members

ygolonac · Jan 22, 2014

Re: Error: Connection Error 595: Connection refused

{
"nodename": "prox2",
"version": 5,
"cluster": { "name": "TELCAT", "version": 5, "nodes": 2, "quorate": 1 },
"nodelist": {

"prox1": { "id": 2, "online": 1, "ip": "x.x.x.x"}
}
}

The ips ara correct

Re: Error: Connection Error 595: Connection refused

I have this issue as well. I can see some of the graphs for a Host when logged into the other host of the cluster, but I can't see the summary.
I think it has something to do with multicast since this is the only server not located on the exact same switch, however, I'm not sure.

When I am logged into zwtProx1 - 2 - 3 I cannot access zwtTEST.
And when I am in zwtTEST, I cannot access zwtProx1 - 2 - 3. zwtTEST is the only host not on the same physical switch, however, zwtTEST is connect via an unmanaged switched.

Re: Error: Connection Error 595: Connection refused

Hi, my two nodes are in the same switch and not use multicast. Use unicast. My error is "Connection refused" and your error is "no route to host"

I don't find the problem.

any idea?

Raymond Burns · Jan 22, 2014

Re: Error: Connection Error 595: Connection refused

In order to properly cluster Proxmox Host, you must have multicast enabled.

ygolonac · Jan 22, 2014

Re: Error: Connection Error 595: Connection refused

i can't. In the datacenter don't permit multicast i the switch

I make test with 2 server in my office and work fine in unicast.

ygolonac · Jan 24, 2014

Re: Error: Connection Error 595: Connection refused

Hi, i don't find the problem...

I check all! any idea?
do you believe that it can be a problem whit the swicth? The problem is exclusive in pveproxy. The cluster, the corosync works fine.

sitius · Jan 24, 2014

Re: Error: Connection Error 595: Connection refused

Hi I had the same problem, please check /etc/hosts at every node you have in cluster. IP address in hosts file must be same as real IP on machine. My problem was that I changed IPs after installation proxmox on nodes.

ygolonac · Jan 24, 2014

Re: Error: Connection Error 595: Connection refused

/etc/host is correct in both servers

ygolonac · Feb 3, 2014

Re: Error: Connection Error 595: Connection refused

the problem was the switch. Arrrrrrrr!!!

tim taler · Feb 7, 2019

Unfortunately I ran into this error too.
I like to run a two node cluster in a hosted environment.
Good news: the cluster is running both nodes are "green" in the webgui, pvecm status looks good etc etc

both nodes have two interfaces, one facing the public internet, and one connected via a crosslink cabel to the other host (10G)
I created the cluster with:

pvecm create <clustername> --bindnet0_addr <ip> --ring0_addr <ip>

directing the cluster internal traffic to the cross linked interface

the firewall allows all traffic between these both (cross linked) interfaces AND all traffic between the two external addresses
IGMP is accepted between the the cross linked interfaces.

Now when I log into the webgui of host A there are both hosts marked "green" on the left menu,
when I click on host A everything works as expected (attributes are displayed in the main window)
when I click on host B I get the "Connection Error 595: Connection refused"
(AND vice versa, I can log into webgui of host B but from there can't access host A)

I have multicast ONLY between then cross linked interfaces,
my provider doesn't allow multicast over the external addresses.

Might the be the reason (and if so that would be ... sad and bad ;-) ?
Or do I miss any special config operation to make it work?

Any hint is appreciated!

TIA

tim taler · Feb 11, 2019

Is there no way to get this working?
As mentioned I have the two systems connected via a crosslink cabel and only the ip address of those interfaces configured as
--bindnet0_addr <ip> --ring0_addr <ip>
