Hi team, We are getting the following error in BE logs while logging into the forest admin portal in Production environments “Gateway response type: DEFAULT\_5XX with status code: 504” PFB the screenshots ![Screenshot 2025-05-13 at 12.06.44 PM](https://europe1.discourse-cdn.com/flex013/uploads/forest/original/2X/b/b6d7a35a9de6f5b9418d46ddc519a9f988ba7e82.jpeg) ![Screenshot 2025-05-13 at 12.06.57 PM](https://europe1.discourse-cdn.com/flex013/uploads/forest/original/2X/0/00652fbc841f76d7bb686eb1d6d5d3b99d4b21a9.jpeg) Note that it is failing only in Production environment under the project.

Hello @Ajith, Could you please share the request and response (if any) of the failing `/authentication` call we can see in your screenshot. Do you have any logs on your production environment agent when trying to connect ? ---

Hi @anon7284711, We are getting CORS issue while authentication API is called. ![Screenshot 2025-05-19 at 3.44.39 PM](https://europe1.discourse-cdn.com/flex013/uploads/forest/original/2X/f/f7909783fea734fe95f43f12f118ed432acad016.png) We are using AWS API gateway for routing for the backend, where are setting the CORS configuration. We are getting the same error if we specify the exact value for ‘Access-Control-Allow-Origin’ as “[https://app.forestadmin.com](https://app.forestadmin.com)”. Can you help here to debug? Note that it was working fine before with ‘Access-Control-Allow-Origin’ as \* ---

Hello @Ajith This may have popped up recently as security policies evolve and get stricter. Could you try to set your custom domain as value ? `https://partner-api.yubbiinvest.com` You might also want to check the environment variable configured in your agent to ensure the value is also present in the `CORS_ORIGINS` variable. ---

Hi @anon7284711 We have set the custom domain name for our AWS API gateway as ‘[https://partner-api.yubiinvest.com](https://partner-api.yubiinvest.com)’. And note that the same is being used for other services. i.e it is working fine. ![image](https://europe1.discourse-cdn.com/flex013/uploads/forest/original/2X/2/250519d751e00bdc8d3e1ff2428a4743d0ecd4ea.png) Also, there is no value set with the environment variable CORS\_ORIGINS. We are using RoR for the forest admin service. ![Screenshot 2025-05-21 at 2.51.00 PM](https://europe1.discourse-cdn.com/flex013/uploads/forest/original/2X/6/69c1b7d800359cbefcdb22a4b7f175c81fa0a6fd.png) ![Screenshot 2025-05-21 at 2.51.48 PM](https://europe1.discourse-cdn.com/flex013/uploads/forest/original/2X/4/4267caf2444fb9fe7bc57fa4288a34fa507791fa.png) Note that the same configurations are present in other environment “QA” of the same project. And it is working fine without any error ---

Sorry I got confused there and thought you had a custom domain setup, indeed you would not need the CORS\_ORIGINS var env then. Are you able to see any logs on your agent when accessing the frontend ? Is there any difference in the setup between your QA and prod envs ? If nothing else, do you have a date in mind of when this started happening ? ---

Hi @anon7284711, 1. Yes, Till now, we have not needed to set up anything in CORS\_ORIGIN. 2. We are able to see logs from the Backend while hitting from the frontend as well as from other api tools like POSTMAN. We are getting the below error ![Screenshot 2025-05-26 at 12.48.26 PM](https://europe1.discourse-cdn.com/flex013/uploads/forest/original/2X/2/22659d8f809b4d6615b4c8155fae552301f2e24d.png) Do you know what causes this? 3. This issue is happening from around April 10th, 2025 ---

Could you confirm to me the last 4 chars of your `FOREST_ENV_SECRET` in both `QA` env and `Production` env. From the logs of our server I can see that your QA env is making requests, but I cannot see a single call made with the `FOREST_ENV_SECRET` of your production environment. ---

PFB Last 4 characters of FOREST\_ENV\_SECRET QA: 3568 PROD: f5bd ---

I can confirm then that on our side we do not have any log with your PROD env secret, I would suggest you to look into your AWS config that could cause error or impede the network between your agent and Forest Admin Servers.
