All this generally means is you've lost your connection to the server for some reason.

Those "Bad_TooManyOperations" errors are a little suspicious because Ignition only tries to create 1 subscription at a time...

Maybe you can disable security on this connection and then get a Wireshark capture where you:

  1. start the capture
  2. edit/save the connection in the Ignition Gateway
  3. stop the capture after these errors have occurred.

Hello Kevin， we also meet the problem for ignition 8.1 ,use the opcua to connect codesys PLC，use uaexpert , these has no error, but switch to ignition ,it get errors:
