Hello person I have a big problem when trying to run my mobile application, after recording all the steps (simple steps) I try to execute the application and it is not executed and not the error, I went to see in the log and had an error: ``` com.kms.katalon.core.exception.StepFailedException: Unable to start app at: 'C:\Users\yan.santos\Downloads\3.3.0.185-pa-release.apk' (Root cause: org.openqa.selenium.WebDriverException: An unknown server-side error occurred while processing the command.

Hi @Yan_Reis, The error mentions a problem with certificate signing: > Unable to start app at: ‘C:\Users\yan.santos\Downloads\3.3.0.185-pa-release.apk’ (Root cause: org.openqa.selenium.WebDriverException: An unknown server-side error occurred while processing the command.

Can you rebuild the APK with signing enabled (or have a developer do so)?

It is increasingly difficult to use katalon, every time it is a different error, before I could record the steps, now I can not even get it anymore, and my katalon is in the current version with appium 1.8.1, I am almost removing the tool from the company and doing not pure, I just had these problems with mobile automation. ![image](https://europe1.discourse-cdn.com/katalon/original/2X/b/bde6c11d082d6b1627d8a0e6ee728ff14295f02c.png) I have already used the procedure that is contained in this post. unsuccessfully!
