client.myserver.com/:1 XMLHttpRequest cannot load <a class="postlink" href="http://api.myserver.com/AbpUserConfiguration/GetAll">http://api.myserver.com/AbpUserConfiguration/GetAll</a>. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://client.myserver.com' is therefore not allowed access. The response had HTTP status code 502.

Hi @antonis,
I think this is related to allowing CORS in your app. Did you configured addresses for *.Web.Host and angular2 client ?
If so, can you share those values (you can replace them with fake addresses, it will be enough) ?
Thanks.

This is the appsettings.json of the Web.Host
"App": { "ServerRootAddress": "http://api.mydomain.com/", "ClientRootAddress": "http://app.mydomain.com", "CorsOrigins": "http://app.mydomain.com" },and the appconfig.json in angular 2 { "remoteServiceBaseUrl": "http://api.mydomain.com", "appBaseUrl": "http://app.mydomain.com" }

Hi @antonis,
Can you share your real config via email and add a screenshot of your client app ?
Thanks.
