Hello,
I have deployed a single machine arcgis enterprise on the AWS, and portal seems to be working well, however the federated server is not working and when I try to login I get the following error
```
Unable to load proxy?_proxyUrl=https://url.com/portal/sharing/generateToken status: 401
```
interestingly the url `https://url.com/portal/sharing/generateToken` seems to have been deprecated and when I use it in the browser I get a warning that says I need to use rest version of the url.
can you please help me find out what is wrong with the installation? thanks
