Issue summary
After upgrading to Ignition 8.3.4 and enabling HA, Gateway scripts do not appear to execute at all.
Current behavior:
-
No compilation errors
-
Project/scripts save correctly
-
Gateway log shows “Restarting scripts…” after saving
-
No further logs are generated
-
Even very simple timer scripts do not fire, e.g.: system.util.getLogger("MES_DEBUG").info("Timer script FIRED!")
No log output is produced.
Important observation
All Gateway scripts appear to be associated only with the Backup gateway, which is currently in COLD state and not the active/operational node.
Master:
Backup:
At the same time:
-
The Designer is correctly connected to the Master
-
The Master is the active gateway
This raises the question of whether the scripts are incorrectly bound to the Backup node and therefore never executed.
Logging behavior
-
Logs appear inconsistently split between Master and Backup
-
When Gateway-script-related logs do appear, they seem visible only on the Backup logger
-
This makes it unclear where scripts are expected to run in the HA setup
Master:
Backup:
Checks already performed
All checks and troubleshooting steps suggested in the following forum topic have already been completed, without resolving the issue:
- Could something have gone wrong during the upgrade or HA configuration?
- Do you see any misconfiguration in the described setup, or are there additional checks we should perform?
- In an HA environment, how should Gateway Scripts be bound to the Master, considering that script-related logs appear only on the Backup?
Any guidance would be appreciated, thank you in advance
