Hello @Hai, Bui Hong ,
Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.
Could you please share some more details about your setup?
I believe the FE VM is in the backend pool of the Application gateway. How is the FE VM fetching data from the BE VM?
Also, could you please confirm if you are seeing the private IP in the URL when accessing the FE from the Vnet or accessing the Application gateway from Internet?
Regards,
Gita
@Hai, Bui Hong , could you please provide an update on this post and share the requested information to further discuss this issue?
Hi,
FE and BE in subnet (10.10.0.0/24), FE is ReactJs, BE is NodeJs.
FE use axios to call api from BE with url http://10.10.0.151:3000/api/users/authen
I config FE in backend pool of Application Gateway.
I seeing the private IP in the URL when accessing Application Gateway from internet.

When accessing Application Gateway http://ip_app_gw:8080 from Internet, , then login, i got an error. Use Developer Tools, on Network tab, i see private request URL to BE
@Hai, Bui Hong , it is difficult to troubleshoot this issue without looking at the actual setup/requests and collection of logs/traffic capture.
Hence, to troubleshoot the exact issue here, we will need a specialized 1:1 session, where a support engineer can have a screen share session to pinpoint the issue. So, if you have a support plan, I request you file a support ticket, else please do let us know, we will try and help you get a one-time free technical support.
Hi, This can happen if you have a hard code on your Backend VM with rewrite requests. This can also happen when you have rewrite rules on Application gateway configured with the Private IP address.
Here my problem, when accessing application gateway http://ip_app_gw:8080, then login, i got an error. Use Developer Tools, on Network tab, i see private request URL to BE, why ? i don't have any rewrite rules on Application gateway.
I don't see the request to appgw Ip on port 8080 on the dev tools. I think you got that page rendered by accessing the site via Application gateway, but there is a 301 redirect from your code which is redirecting the traffic to the Private IP
from code in FE, i call direct to the private ip of BE, and i want to access FE from Internet, i use Application Gateway, but i got an error.
my configuration is not correct or I misunderstood the role of Application Gateway?
I am more interested in what is the URL mentioned on the Location header of the request redirect.
