A2A error Authorization is denied for this request (4383950)

When trying to run the Curl command to get the password from A2A credential retrieval endpoint the following error appears:

curl -v -X get "https://{Safeguard_IP_or_Hotsname}/service/a2a/v4/Credentials?type=Password" -H "Authorization: A2A ###########################################=" --cert Certificate.crt --key Certificate.key --insecure

Code":60094,"Message":"Authorization is denied for this request.

HTTP/2 was used by default and this is currently not a supported HTTP version

STATUS

Enhancement Request # 461690 was submitted to add support of HTTP/2 for Certificate or A2A authentication in a future release of SPP subject to product management approval.

WORKAROUND:

Force the Curl command to use HTTP1.1 - for example:

curl --http1.1 -v -X get "https://{Safeguard_IP_or_Hotsname}/service/a2a/v4/Credentials?type=Password" -H "Authorization: A2A ###########################################=" --cert Certificate.crt --key Certificate.key --insecure
