I’m working with a pair of groov EPICs running Ignition Edge as a redundant master and backup gateway. I have them configured with Tag History Sync to another Ignition Gateway elsewhere in our environment. All three are in the same Gateway Network and the remote server’s security zone is set up to allow both EPICs to connect. When I fail over from the master to the backup, it takes over as expected. I can see the local version of the tags history on the backup gateway. But, the backup gateway does not push the values over to the remote server. I have two other Edge pairs set up for testing, and those both fail over and post from the backup without any issue.
As a note: this did work when I first configured it. As part of testing, I forced a resync of the backup from the master. Ever since then, the backup will not post to the remote server. I’ve tried deleting the Gateway Network entries and recreating them as well as reconfiguring the security zone. Since I have not seen this issue with our other Edge devices, I figured I would post here versus posting on Ignition’s forum.
