Symptom

Webgui Fiori application screen shows loading, and no response even after waiting for long time

When using the search function, click on the dropdown list or during transactions entries, the system shows endless loading status.

Environment

S/4HANA and Marketing Cloud Systems (All Version)

Cause

The cause of the issue is that Antivirus software ESET is blocking system URL like myXXXXXX.s4hana.ondemand.com and causing this endless loading or getting stuck at a fiori screen. Please follow below mentioned procedure in your antivirus software to resolve such issues.

Resolution

There are two steps you need to perform in your anti-virus software for this issue to be resolved:

1. Perform whitelisting of URL in your ESET anti-virus software so that such URL is not blocked. For whitelisting please use functionality in ESET of 'URL addresses list'. In this section you can specify lists of HTTP addresses that will be blocked, allowed or included from checking. List of allowed addresses – If allow access only to HTTP addresses in the list of allowed addresses is enabled and the list of blocked addresses contains * (match everything), the user will be allowed to access addresses specified in this list only. The addresses in this list are allowed even if they are included in the list of blocked addresses. So, add your S/4HANA system URL myXXXXXX.s4hana.ondemand.com/ui in this list of allowed addresses.
