3126093 - HTTP/1.1 is used although HTTP/2 is enabled in SAP NetWeaver system

Symptom

While using an internet browser to access SAP, it is observed that HTTP/1.1 is used despite that HTTP/2 is configured at SAP.

The issue happens only when using an internet browser based on Chromium (e.g., Google Chrome, Microsoft Edge).

In addition, the authentication method used is SPNego.

If another browser is used (e.g., Mozilla FireFox), the issue does not happen.

If a Chromium based browser is used to access a resource that does not require (SPNego) authentication (e.g., "/sap/public/icman/ping"), then HTTP/2 is used as expected.
