I have a few edge gateways setup on some PCs, they are all setup as realtime tag providers to a central gateway. After upgrading one of the edge PCs I can no longer view or edit the tags from my central gateway. I have gone through the gateway network settings on both ends and approved the certificates from the new PC. My swap process was to create a gateway backup on the old edge PC, transfer the license then restore the gateway backup to the new edge PC, approve the new gateway network connections . Are there some steps I am missing to get this connection restored? Right now when I am in the designer in a central project under the tag browser when I click the dropdown and select this edge provider I get an error “com.inductiveautomation.ignition.client.gateway\_interface.GatewayException: java.lang.SecurityException: Security settings do not allow access to tag provider ‘edge’.” I have tried disabling the edge provider at my central gateway and re-enabling it. When I disable the edge provider from my Central gateways realtime tag providers it disappears from my central tag browser dropdown and shows up when I re-enable it so that seems to be working. Should I delete the edge tag provider on my central gateway and re-create it? The naming convention is the exact same so I don’t think I should have to do this. On my edge gateway the ‘service security’ default policy has been modified so in the tag access section I have everything set to ‘ReadWriteEdit’ and this configuration had been running for months on the old PC. Any ideas? TIA ---

Check security zones. Depending on how zones are defined, it’s possible your replacement Edge gateway is not falling into the expected security zone. ---

I have the default security zones on my edge and central gateways. ---

The problem turned out to be a licensing problem with the MQTT transmission module. I had to reinstall that module.
