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


The cause of the issue is that Antivirus software ESET is blocking system URL like 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.


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

1. Perform allowlisting of URL in your ESET anti-virus software so that such URL is not blocked. For allowlisting 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 in this list of allowed addresses.


2.  Allowlist the certificate in ESET Endpoint Antivirus software. This could be achieved by using List of known certificates option in ESET antivirus software.

The List of known certificates can be used to customize ESET Endpoint Security behavior for specific SSL certificates, and to remember actions chosen if Interactive mode is selected in SSL/TLS protocol filtering mode. The list can be viewed and edited in Advanced setup (F5) > Web and email > SSL/TLS > List of known certificates.

The List of known certificates window consists of:


Name – Name of the certificate.

Certificate issuer – Name of the certificate creator.

Certificate subject – The subject field identifies the entity associated with the public key stored in the subject public key field.

Access – Select Allow or Block as the Access action to allow/block communication secured by this certificate regardless of its trustworthiness. Select Auto to allow trusted certificates and ask for untrusted ones. Select Ask to always ask user what to do.

Scan – Select Scan or Ignore as the Scan action to scan or ignore communication secured by this certificate. Select Auto to scan in automatic mode and ask in interactive mode. Select Ask to always ask the user what to do.

 Control elements

Add – A certificate can be loaded manually as a file with the extension .cer, .crt or .pem. Click File to upload a local certificate or click URL to specify the location of a certificate online.

Edit – Select the certificate that you want to configure and click Edit.
