3774931 - Blue blank page is displayed after login to SAP Analytics Cloud (SAC) on CN40 in certain regions

Symptom

  • After successful login to SAP Analytics Cloud (SAC) on CN40, a blue blank page appears and the home page does not load. 
  • In HAR file, the HTTP request to either of the following URLs doesn't return any response (either response header nor response content)
    • https://assets.sapanalyticscloud.cn/production/uiAssets-<version>/uiAssets/build-manifest.json
    • https://assets-tencent.sapanalyticscloud.cn/production/uiAssets-<version>/uiAssets/build-manifest.json
  • In Console log of Development tool, the following error could be observed:
       Device API logging initialized - DEVICE
       orcaBaseHelpers.js:632 Could not get the manifest file: 0
      orcaBaseHelpers.js:635 
      GET https://assets-tencent.sapanalyticscloud.cn/production/uiAssets-<version>/uiAssets/build-manifest.json net::ERR_CONNECTION_RESET
  • Directly opening the manifest URL in a browser fails on both desktop and mobile devices

Environment

  • SAP Analytics Cloud, Enterprise Edition
  • AliCloud (CN40) datacenter
  • Certain regions in China

Reproducing the Issue

  1. Try to access any SAC tenant running on CN40.
  2. Enter credentials in logon page.
    => After successful authentication and redirecting back to SAC, blue blank page is displayed and home page cannot be loaded.

Cause

The UI assets manifest at https://assets-tencent.sapanalyticscloud.cn/production/uiAssets-<version>/uiAssets/build-manifest.json is not reachable from the affected regions  (not only your company but also the whole location - maybe city or province), preventing the application from loading required resources.

Resolution

  • Please run the following command to identify which network layer would be the cause:
Command Line TestTypical Error

ping assets-tencent.sapanalyticscloud.cn

Ping request could not find assets-tencent.sapanalyticscloud.cn
Destination host unreachable
Request timed out

nslookup assets-tencent.sapanalyticscloud.cn

* Recv failure: Connection was reset
* schannel: failed to receive handshake, SSL/TLS connection failed 

openssl s_client -connect assets-tencent.sapanalyticscloud.cn:443no peer certificate available
SSL handshake has read 0 bytes and written 1574 bytes 

  • If either of them fails, this indicates a local network or ISP-level reachability issue to assets-tencent.sapanalyticscloud.cn. Please engage your internal IT team to coordinate with the local ISP to restore normal access so that https://assets-tencent.sapanalyticscloud.cn/production/uiAssets-<version>/uiAssets/build-manifest.json is accessible from browsers. After access is restored, log in to SAC again and confirm the home page loads successfully.
