I am trying to connect Foundry to Cafe24 API (artplex.cafe24api.com:443) and the egress policy is already approved. However, the OAuth2 authorization process fails with the following error: ‘Unhandled runtime exception while calling oauth2 server via egress-proxy’. Error ID: ed56413a-5394-4a35-b1c9-1cf294bcbaf1, Client RID: ri.oauth2-clients.main.oauth2-outbound-app.8346cd8e-d186-49ce-bde9-6178da73051e. All OAuth2 endpoints, client info, and redirect URIs have been double-checked. What could be causing this and how can I resolve it?
