Hi all, I am trying to set up Redundancy in Ignition 8 for some testing using two VMs but haven't had much luck so far. I followed the usual steps for setting up redundancy also refer to the thread > [@Redundancy in beta?](http://forum.inductiveautomation.com/t/redundancy-in-beta/21168): > > I have come across an issue trying to enable redundancy, and thought occurred that this may not be enabled in the beta. So I would like to confirm before spending any more time trying to problem solve. I have attempted to setup redundancy on an existing server, and just now a fresh install. for setting up the Gateway Network Connections but the two gateways haven't been able to connect. In Gateway Network I keep getting the following error: ![Connection%20Details](https://us1.discourse-cdn.com/inductiveautomation/original/2X/b/b9efc7df4bfdb7a8a51a4b93127fd400a2fb6014.png) Windows firewall is completely turned off and I have no issues with pinging or browsing between the gateways. Testing environment: VMs - Windows 7 pro 64-bit Ignition version - Version: 8.0.0 (b2019040718) with trial license Any suggestions would be much appreciated!! ---

Have you accepted the incoming certificate on the opposite gateway? Go to the Gateway Network section in Configure, then the Incoming tab. ---

Hi Paul, Thanks for you reply. That’s the thing I forgot to mention. When I go into the Incoming Connections tab, I don’t see the connection request from the Backup Gateway. I’ve tried changing the Connection Policy to Unrestricted and SpecifiedList but that didn’t make any difference. I’ve included some screenshots of the settings and status. Is there any other crucial settings I might be missing?

Can you confirm that the master and backup gateways are set up on separate machines? It looks like they both have the same IP address and port. ---

I created the Backup Gateway VM by making a copy of the Master Gateway VM. First thing I do is changing the MAC address of the virtual network card on the Backup Gwy VM. In the Backup Gwy VM, I then change the following: - PC Name - IP Address and make sure I can ping each other and brows each other’s gateway - Gateway name, and make sure the it’s pointing to the Master Gateway IP in the Redundancy setting - I then change the Redundancy role to Backup I went through the same process using Ignition 7.9.10 and no issues with getting the redundancy to work. I’ve just installed Ignition 8.0.1 and went through the same process but still no luck… The Backup gateway is definitely trying to make connection to the Master Gateway but it’s keeps on faulting on this **OutgoingConnect(): web socket connection could not be established** error. Could it be some Windows or SSL thing in the background that’s blocking the connections? ---

Status Update… I did a fresh install of Ignition 8.0.1 for the Backup Gateway on a different VM and a new certificate with a different serial number popped in Master Gateway’s Incoming Connections tab and now the peer connection is good on both gateways. It looks like the problem was because I duplicated the Master Gateway’s VM and both VMs had the same self certificate… Thanks a lot for all your help!! ---

Is there a way to create a new certificate on the backup? I have a similar situation, but I have two physical Linux machines that were setup with a Master ISO (not sure if that’s the correct term) and they both have the same certificate. I regenerated the opc-ua certificates, but those don’t seem to be the certificates that are being used for redundancy.
