Design Launcher using IP for backup

Ignition
1

I am trying to setup new redundant pair gateway instance using 8.1.45. I have them both setup to use self signed SSL certificates. When I try to add the gateway to the designer launcher it first trusts the masters gateway certificate and then prompts that the backup certificate needs to be trusted. On trusting the backup I receive the error

javax.net.ssl.SSLHandshakeExcetoin: No subject alternative names matching IP address "X.X.X.X" found

When I look at the designer-launcher.json I see the redundant gateways has the IP address of the backup gateway. I have tried to manually change it to the host name of the backup but the trusting of the cert still fails and then when I close the launcher the json file changes back to the IP address. Am I missing some where I have to tell the gateway or the launcher to use the hostname of the backup gateway?

On both master and backup you'll want to go to Web Server settings and turn off "Autodetect HTTP Address" and then specify the actual IP/hostname in "Public Address".

and you do have to make sure that the IP or hostname you're accessing these gateways at is actually in each of the corresponding certificates.
