Issue
An "Internal Server Error 500" message appears when attempting to access a Niagara G3 ENC station via a web browser.
Environment
- Niagara G3 ENC station
- Web browser
Cause
Typically, this issue is caused by the Module Content Filter Level in the ENC being set to "RUNTIME". In order for an ENC to host Web Services, the ENC needs to have the Module Content Filter Level set to "UI+RUNTIME".
Resolution
Use the Commissioning Wizard in the Platform Administration section of the ENC's Platform to set the Module Content Filter Level to "UI+RUNTIME".
In some cases, the error message persists even after re-commissioning per the above instructions. To correct this problem, go to the Software Manager in the ENC's Platform, highlight all the modules that are marked "Up To Date", and re-install them.
