Add platform android : Failed because of upload images error

Iam using ionic 3 and every time when i execute ionic cordova platform add android I get the below pasted error. Iam using Azure pipeline to build the android apk

Is the server down? How can it be solved? It was working few days back and there is no problem with images

ionic cordova resources android --force
:heavy_check_mark: Collecting resource configuration and source images - done!
:heavy_check_mark: Filtering out image resources that do not need regeneration - done!
:heavy_multiplication_x: Uploading source images to prepare for transformations - failed!
HTTP Error 503: POST


I would suggest reading this thread.
