Repository non operational?

I’m receiving this from few hours. Before everything was fine.

* Where:
Build file '/home/bz-user/bayzat/bayzat-be-kt/build.gradle.kts' line: 6

* What went wrong:
Error resolving plugin [id: 'org.jetbrains.kotlin.plugin.spring', version: '1.3.72']
> Could not resolve all dependencies for configuration 'detachedConfiguration3'.
   > Could not determine artifacts for org.jetbrains.kotlin.plugin.spring:org.jetbrains.kotlin.plugin.spring.gradle.plugin:1.3.72
