jitpack.io status code 521 from server Android Studio-CodePudding

My app was working great in the past. From this morning suddenly when I run the app from Android Studio this error shows:

Could not GET 'https://jitpack.io/androidx/fragment/fragment/maven-metadata.xml'. Received status code 521 from server: 
Disable Gradle 'offline mode' and sync project

However, Gradle 'offline mode' is disabled: Graddle toolbar

Is this a problem of jitpack.io? If so, when is expected to be solved? What can I do meanwhile?

If I able Gradle 'offline mode' when running this other error occurs:

Could not determine the dependencies of task ':app:compileDebugJavaWithJavac'.

Any comment will be welcome I really dont know what to do, already looked similar problems but anything worked. Thank you!

CodePudding user response：

It seems the jitpack server is currently getting through some problems and we can't use it right now.

CodePudding user response：

It looks like their system is down, but there's been no response from Jitpack team yet - here's the issue created in their repo.
