Remote Test Lab

What the error “Check certificate error [-12] failed” means??

I’m trying to install my app, but I keep getting this error… It is not my file that has a problem, because yesterday I installed the exactly same file and it worked…

Thank you for your time!

Do a Google Search for Tizen Certificate Error -12
One that may be the issue with RTL is you didn’t remove the old app on the test device.
There are others responses some say just try again.

Anyway do a Google search this seems to be fairly common and various reponses.

Hope this helps
