Could not GET ...... Received status code 403 from server: Forbidden

I'm getting the following error when I try to build an application which contains the library.
I think around a month ago I could still build, but now I'm getting this issue:

FAILURE: Build failed with an exception.

• What went wrong:
  Could not determine the dependencies of task ':app:lintVitalRelease'.

Could not resolve all artifacts for configuration ':app:debugCompileClasspath'.
Could not download simple-encryptor-lib-1.1.3.jar (com.mobapphome.library:simple-encryptor-lib:1.1.3)
> Could not get resource 'https://dl.bintray.com/hummatli/maven/com/mobapphome/library/simple-encryptor-lib/1.1.3/simple-encryptor-lib-1.1.3.jar'.

Is this a know problem?

What could be the fix for this?

BTW in my build.gradle I'm still using jcenter
