Hello @Tom, Thanks for your feedback! Your browser is getting a 502 error for the request that it’s sending `OPTIONS https://admin.production.panopli.co/forest/authentication` This request is the first one that is launched to your agent before anything else. The 502 error indicates a “Bad gateway error”, meaning that your reverse proxy cannot access to your agent to redirect the request. Can you first test if you can access this agent from your browser, at the addess `https://admin.production.panopli.com`? You should see " Your application is running!`. If it’s not the case, then I guess that something is wrong with your configuration. ---

Hello @GuillaumeGautreau 🙂 Indeed the [admin.production.panopli.co](http://admin.production.panopli.co) isn’t accessible 🤔 Everything was fine in dev mod, any clues on what could break ? ---

Hello, a 502 error indicates one of the following: - Either your agent is not running - Or it’s listening on a port that is not the one you configured in nginx/apache I tested again to access your agent, and I don’t have the same error. Do you have the same error when trying to login in? ---

I rolled back to v5 to make it work ( we have a very old project 😅 ) The agent in v7 seems to init correctly as we get the welcome logs " Your admin panel is available here: [https://app.forestadmin.com/projects](https://app.forestadmin.com/projects)" on my container logger. Then i get 404 everytime i try to authenticate ---

Do you have the 404 error with the v7 or v5? ---

The v5 is working fine, i log in no pb . The 404 occurs with v7 ---

Ok, then the error is no more a 502 as it was at the beginning. Now, I suppose that the `OPTIONS` request receives a valid response, but you get a 404 on `/forest/session`? As you are modifying a production environment, you have to copy the file `forestadmin-schema` from the dev environment that you already migrated and that you validated. This file contains a declaration of the version that is being used by the server, and this version is used to determine which endpoint to use when logging in (it changed in v7). ---

Hello , i apologize i was on holiday :slight\_smile We did not receive any OPTIONS . Here’s my container logs wen i’m building the app ![container](https://europe1.discourse-cdn.com/flex013/uploads/forest/original/2X/4/4d8ccbd8806cf6e61a132727c1fe26b522823099.png) The 502 from [admin.production.panopli.co](http://admin.production.panopli.co) is from our load balancer ( it cannot find any healthy pod ). I have no clue on what is going on . The V7 upgrade works fine on localhost, no error message and i can use the app. ---

Hello @Tom, Can you open the developer tools in your browser, select the network tab and try to login to your agent? Then, please share with us the details about the queries that are failing (request & response headers and content). Thanks ---

I’m not sure of what you’r asking me . We have an “old” project ( i guess we start on V2 ) . We are currently on V5 ( i rolled back the V7 update ) ---

Ok, then the route `/` is probably not defined on the backend. As you get a 404 error, it means that a backend is correctly responding. Now, let’s move on to the next topic: authentication. Can you please open the right environment on your project, in your browser, open the developer tools and identify the requests that are failing during the authentication? ---

Hello again 🙂 Sorry for late response . Thank you for your help @GuillaumeGautreau , it was actually an healtcheck issue , we were trying on / and we get no reponses ( as it wasn’t define on the backend) . Changing the healtcheck url on our side solve the problem Have a nice day 🙂
