URI contains reserved characters such as "$" and certain firewall rules block these URI's.
Environment
DXP 7.4
Resolution
Many URL schemes reserve certain characters for a special meaning.
However, this is not true for reserved characters:
Encoding a character reserved for a particular scheme may change the semantics of a URL.
Thus, only alphanumerics, special characters "$-_.+!*'(),", and reserved characters used for their reserved purposes may be used unencoded within a URL.
Referring to all the above-mentioned information, the root cause of the issue is in the settings of the firewall, which has to be configured accordingly.
