Proxy configurations when using ServiceClient

[bjm3819]

Were using ServiceClient in a web app. The web app lives in a EC2. The company uses a proxy.
I also have a .net core console app, this app on the same EC2 can get out to the dataverse/dynamics endpoint when setting the env http proxy variables. However, the web site cannot, it's httpclient connection under the hood of the ServiceClient type times out.

What can we do?
Were using a Amazon Linux 2023.3.20240312 and have also tried Red Hat Enterprise Linux 8.10 (Ootpa)
