Studio Pro - server failed to start. see details for the server log

0
Creating a blank app and running it results in the following popup in StudioPro:   There’s nothing in the Studio Pro console. Google searches and searches on the forum indicate this issue has been encountered for a while across various versions of Studio Pro. However, there aren’t many with successful resolutions. I get similar errors on version 9.15, 9.13.1, 9.12.4 of Studio Pro. Appreciate any pointers/assistance in resolving this. Thanks!

Thanks for the pointer @Srilatha.


Any additional pointers as to where I need to “add or update the environment variable NO_PROXY”

Is this in a config file (if so, which one?) or thru something in Studio Pro?

Thnx!

Honestly speaking i never encountered this issue. But i think they are referring to this very place in the Config. Can you try the above?

Thanks Ganesh. 

I tried this.


No luck! Same error.

 

I do see the follow after enabling Debug (file studiopro.exe.nlog) in the Studio Pro log (Help - Open Log File Directory - log.txt)

Not sure if this error was present before or only after I entered the proxy value!!

Thanks Ganesh.
This was a 'blank' app created afresh.

I suspect that it's an issue with my system/network, too.

Thanks for your help. I will post updates on this thread if/when I address the issue.
