Nothing Loads on certain networks

Greetings. We noticed that we could not get the UI to load behind our firewall (Palo Alto) and I can't even get it to load from a WVD VM in Azure using chrome or edge. However, on my home network it's fine. A palo engineer had found that there is a mis-match with packets being sent back from the app service. We can log in but nothing displays. We found that on networks where it does load, the below values are filled with the user, token, etc. What is shown is when it doesn't load. This is from https://-api.azurewebsites.net//api/Login/PostLogin

{UserName: null, Email: null, Access_Token: null, Id_Token: null, Refresh_Token: null, Code: null,…}
UserName: null
Email: null
Access_Token: null
Id_Token: null
Refresh_Token: null
Code: null
RoleAssignment: null
TenantGroups: null
Error: {StatusCode: 400, Message: "Invalid Code"}
ApplicationVersion: null
GitAppVersion: null
GithubUpdateDeployUrl: null


Start by reproducing the failure against the reported /api/Login/PostLogin endpoint from a home network and from the Palo Alto or Azure WVD network, then inspect the returned authentication fields and 400 Invalid Code response. Done means the UI loads successfully on the affected networks and the login response contains the expected user and token values.
