Call to download server failed (HTTP error code: 403).

The installer for a compiled (using R2015b) app, that has been distributed to many customers for several years, is suddenly (noticed in last couple of days) throwing the above exception. This has happened from multiple sites, domestic and international. The insaller is set up to download the MCR from MathWorks.

Is anyone aware of any MathWorks, Windows (10, 11) updates that might be causing this?

Thanks! It's a bit urgent!!

Did you solve this problem?

[Walter Roberson]

I wonder if this is related to TLS1.2 support? Did you specifically build the executable with the appropriate java.opts file?

Yongtao, not yet. MathWorks are looking into the issue.

Walter, thank you for the comment. I will check that but the build hasn't changed in three years - it just stopped working one day a couple of weeks ago.

UPDATE I tried adding the java.opts file to my startup folder. ML sees it but there is no improvement. Good idea, though, thanks.

Hi all, I am having the same problem with an App compiled with 2015b. Have not resolved the issue yet, so I'm following along here as well.

[Dave Watson]

Parker, MathWorks are investigating this. Will keep you inflormed as I am. The story, so far, is that it's likely not you/us. Thanks for adding your name.

I encounter the same error with an application built with matlab R2019a...

I recompile the application with R2023b and there is no problem with this version.

Thanks, did this just start happening? We believe it started sometime after 11/26?
