Error while running app in version 9.11.1

5
We recently upgraded mendix studio pro from version 9.4.0 to 9.11.1. Since then, getting the below error while running and the server isn’t starting. 2022-03-16 06:03:42.245 INFO - M2EE: Added admin request handler '/prometheus' with servlet class 'com.mendix.metrics.prometheus.PrometheusServlet' [rtlauncher:container$] INFO Container start took 2105. Ready to accept admin requests. Tried creating a new app in version 9.11 and running that gives the same error as above.

Hi everyone,

I was able to find what’s going on. The studio pro try to use the proxy to call 127.0.0.1.

To handle it, just add or update the environment variable NO_PROXY to add 127.0.0.1
after I guess it will work

Please do the following:

Go to your Mendix\9.11.1.40456\modeler folder, then finding the studiopro.exe.nlog file, and then, on line 8, changing the minlevel to "Trace" (or "Debug"). 
Afterwards, you would need to reproduce the issue again to get all the logs.
Please confirm what is present in the logs?

Hello,

 

To share the knowledge, for me, it was a network problem. No need to change port or anything. Check your connection (VPN..)

Hi Latika,

This is no error, these are normal startup messages. What are you seeing when opening the page in a browser?
