I have seen this before, where the default OPC-UA server faults after restoring a gateway backup. I recall seeing this in one of the workshops at ICC 2015 and Travis had to do some Ninja behind the scenes work to get it to work.
In the past the only way I have been able to fix this is to export my project and tags, reinstall Ignition and rebuild customized gateway settings from scratch.
is there a Ninja trick I can do without having to rebuild the gateway?
