AZ Devops 2019 Update1.1 via Azure App Proxy, not full webpage content loaded

Question

Hey Team,

I've got Devops Server 2019 Update 1.1 installed on-prem and exposed via Azure App Proxy. HTTPS is configured as well as all COARS-related issues solved. TFS is reachable.
Now, when I attempt to load the web site using AppProxy external address, not entire web content is loaded, as my web browser for a few GET requests done against the DevOps page, tries to resolve internal FQDNs, which are not registered in public DNS. Obviously my browser/PC cannot resolve internal on-prem addresses. I believe this is an App Proxy bug in a scenario combined with DevOps Server.
I am trying to understand if DevOps Server is going to work in this setup to communicate it back to my customer.

CHROM debugger output:
GET _static/_ext/ms.vss-features/ui-fileinput-content/ms.vss-features.ui-fileinput-content.es6.juv2Mex8d1OWccNC.min.js net::ERR_NAME_NOT_RESOLVED

As I got stuck, your help would be much appreciated!

Hi @MaciejWidomski-1709,

Azure DevOps Server is currently not supported in the Q&A forums, the supported products are listed over here https://learn.microsoft.com/en-us/answers/products (more to be added later on).

You can ask the experts in the dedicated Azure DevOps Server forum over here:

Hey @Leon Laude

My question is towards Application Proxy as a feature of Azure AD, not the DevOps Server itself. I believe this is the right forum to ask AAD-related questions?
As stated in my previous post - it's been already discussed on the VS forum and the outcome is that the problem is NOT related to TFS/VS, but to the App Proxy.

Hope you can provide some insight here.

Hi,

For everyone dealing with this issue, what you can do is have the same FQDN external and internal for the Azure DevOps server. And if you want the users to always access the app through the internet, you can delete the internal DNS record and add a record in the host file on the on-prem server where the connector was installed
