Hi. The problem is not with the certificates anymore. The offsite transporter and repository are not accessible from the On Site Synology NAS install.
The connection to "X.X.X.X:9446" was refused. Make sure the provided information is correct and the connection is not blocked.
I have setup a Telnet session and can successfully connect to that IP form my onsite network using port 9446
I have a ticket open but they have told me it is off to development to work on the issue. I currently have no offsite backups and entering my 2nd week.
