Hi @gwootton ,
thanks for your reply. I already engage SAS Support.
I will continue to investigate at my side based on your findings.
I already checked the internal/external connection and the configuration are consistent in SMC.
Certificates are also ok as I can access others web applications.
Maybe something wrong in proxies... or somewhere else
I will let you know if I find (or SAS TechSupport) the root cause of my issue
