Hi!
I tried the redundancy to see how it works with a dummy project, when the client loses the communication with the master ( the master is down) I have to restart the client so it connects to the slave.
Is it possible to do this automatically, so the clients don’t have to restart to see all the data, it does automatically when the master is up again, the client reconnect to the master.
Best regards
It sounds like you have both set up as masters. Be sure to set up your backup gateway as the backup and your master as the master in their respective gateway configuration.
The only other configurations are to set up the backup node address in the master and whether or not you want the master to automatically take back over once it comes back online.
Good luck!

Nope, one is as Master and the other as backup Cold.
Both has the same ip address in the field Master Node Address.
When i chen the status i see that the both Ignition are connected one as master and the other as Backup. the clients connection shows just in the master, if i turn off the master the backsup shows 0 client connected, so i have to restart the clients
Under redundancy, enter each servers IP addresses on there respective hosts. You will have to disable the auto addressing scheme. Redundancy is about the only thing that is server specific. Please post a snap shot of each redundancy page please.
I have attached files from the configuration page and from what i see at the satus page of both Ignition and the clients when the Master is connected and when the backup is connected. All work if I click on the configuration page Force a fail-over backup, but if i stopp the Master server or if i shut down the server then it doesn’t connect to the backup. The weird think is that it worked today two times, then i restart the client without changing something in the configuration or in the designer and it stoped working
this is what the console shows:

like kyle said, you need to uncheck “autodetect http address” and then add entries for both of your server ip addresses or domain names along with the correct http and https port numbers in the spot right below.
