Web App is not installing

Hi all,

Please note all of a sudden App Management is not installing the web app. The web app is a plain html to provide FAQ for my DHIS2 users and was installed long time ago. I enhanced the same with one more page and redeployed but it is refusing to deploy now. It simply says “Uploading” for several seconds and then finally says “Failed to install App”.

We are using DHIS2 2.29. I am trying to install a Standard App.

Any help to resolve this issue is highly appreciated. Thanks in advance.
