Intermittent Generic Login Error: “An error occurred, please contact your system administrator.

0
Hi ,We are intermittently facing a generic Mendix error popup during login:“An error occurred, please contact your system administrator.”Sometimes the user gets this popup, and other times after login they are redirected back to the start screen.The issue is not consistently reproducible and seems to happen only for certain users occasionally.We would like to understand:What are the most common root causes for this generic login error in Mendix?Which logs/categories should we specifically monitor to identify the exact issue?Is there a way to replace this generic popup with a more meaningful/custom error message?How can we proactively identify where and when such errors may occur for users?Any guidance or troubleshooting suggestions would be helpful.Thanks!

Hi Reemali,


Please try connecting the debugger to the flows, if any are configured on the default home page. If not, check whether there are any role-based home page flows and add the breakpoint to debug if there to identify the root cause, provided the issue is reproducible.

Additionally, try changing the log level to Trace or Debug for deeper analysis of the issue. Also, please inspect the application from the browser and check the Console tab to see if there are any client-side errors.


Further, I would recommend adding an error handler in the flows wherever there is a possibility of the issue recurring, so that similar scenarios can be handled more effectively in the future.
