Application launched, but unable to connect using port 16256.

Hi Masters!

I have had Windows VPS hosting running in Windows server 2008.
The technical team of the hosting provider set my server to accommodate XOJO program.

It run well under XOJO ver 2.3!

But when I use ver 2016 1.1, it pop an error saying >> Application launched, but unable to connect using port 16256.

What is the problem? Anybody please help.

Anybody can help me?

It would be helpful to know which year this was.

But anyway, the error you describe could be a bunch of things. Usually it’s that the app can’t launch. Since 2016r1 added dependencies for Windows, make sure you run the installer from your extras folder on that server.

Hi Greg,

Thank you for your reply.

xojo 2.3 was 2015. It works fine on Windows 2008 server.

Kindly please elaborate this. What Installer you mean? >>“make sure you run the installer from your extras folder on that server.”

More info here: Windows Universal Runtime

I think I found the culprit but I don’t know how to resolve this.

I noticed that once I add the database accessing features to my xojo program, it produce the “Application launched, but unable to connect using port 16256.”

Please help.

Problem fixed!

Allen S. (technical person) from www.accuwebhosting.com set permission to IIS_USR. That’s it! it works fine now!

I am now running my XOJO application on Windows Server 2008 using MS-SQL2008R2 database!

GREAT!
