Hi @Ramesh K , one possible solution is to ensure that the redirect URI in your Azure AD application registration is configured correctly.
If you still face issues, you might want to check the Azure AD Application Proxy settings and ensure that the internal URL includes all the relevant links for the application. Additionally, you can consider using custom domains to publish your applications, which allows the same URL to be used both internally and externally.
If these options don't resolve the issue, you can explore enabling inline link translation using Intune Managed Browser, My Apps extension, or the link translation setting on your application. For more information on redirecting hardcoded links for apps published with Azure AD Application Proxy, you can refer to this guide.
If this still doesn't work please let me know and I can help you further.
