I am using Mender Production Server. The server configurations were as follows mongo version: 3.6 mender version: 2.4 I used following link to upgrade the server > **[Upgrading | Mender documentation](https://docs.mender.io/2.5/server-installation/upgrading)** and after upgrading the server the updated version is as follows mongo: 4.4 mender version: 2.5 I received no errors during the upgrading, but after starting the server there is no dashboard it’s a blank white page. I am not able to understand the cause of this issue. I am attaching few snapshots which might help you to understand the cause. As you can refer to the left side of the ui\_output image, the complete screen is just blank no dashboard at all. Please let me know if I am missing something here. ![docker_ps_output](https://canada1.discourse-cdn.com/flex036/uploads/mender/original/1X/101bc1f963580037c634d3006843270daa50977a.png) ![run_command](https://canada1.discourse-cdn.com/flex036/uploads/mender/original/1X/14dd2c731db11962a56d723c5976b710eca595df.png) ![ui_output](https://canada1.discourse-cdn.com/flex036/uploads/mender/original/1X/9832ee3c8cc4ea783d8b790d843f7ab05b8de27f.png) ---

Hi @vishruti It looks like you have a syntax error in the gui container’s env.js file (the second error is a consequence of the first one). Have you overwritten the Docker [entrypoint](https://github.com/mendersoftware/gui/blob/2.5.x/entrypoint.sh) for the gui container in your production setup? ---

Hi @alfrunes, I don’t recall overwriting an entrypoint for gui container. I followed the exact same steps as per the documentation. Can you please let me know the steps I need to follow to resolve this issue. ---

I’m not able to reproduce this error locally. Can you inspect the syntax error in the `env.js` file? You can click the hyperlink from the debug console or run `docker exec menderproduction_mender-gui_1 cat env.js`. If I replicated your environment correctly, it should look something along the lines of: ```auto mender_environment = { hostAddress: "", hostedAnnouncement: "", isDemoMode: "", features: { hasMultitenancy: "", isEnterprise: "", isHosted: "" }, trackerCode: "", recaptchaSiteKey: "", stripeAPIKey: "", integrationVersion: "2.5.0", menderVersion: "2.4.x", menderArtifactVersion: "3.4.x", menderDebPackageVersion: "2.4.x", metaMenderVersion: "", services: { deploymentsVersion: "", deviceauthVersion: "", guiVersion: "2.5.x_9282911a3cff7e60098436f75e4cab968bd898a4", inventoryVersion: "" }, demoArtifactPort: "", disableOnboarding: "" } ``` ---

Hi @alfrunes, I checked the env.js file. The host address is not the public IP of my server. I have attached a snapshot for the same. I am not able to login to the container as it is in exited state. please let me know how can I change this IP address as per the public Ip of my server ![envjs](https://canada1.discourse-cdn.com/flex036/uploads/mender/original/2X/4/406514c0b2f7aca29ab7847f7d7d95b8013ff18e.png) ---

I have changed the ip as per my server’s public IP and on reloading the site I get following error and the dashbord is blank as well ![userReducerjs](https://canada1.discourse-cdn.com/flex036/uploads/mender/original/2X/b/b4beb8a12ba669a48dca3e3c859f03e33a94fa8f.png) ---

As you can see there is a syntax error on line 14 and 17. Somehow the environment variable setting these two values ([MENDER\_VERSION](https://github.com/mendersoftware/integration/blob/master/production/run#L11)) is assigned the string “2.3.0\n2.4.0”. It might be that a merge conflict to the integration repository has introduced an error to [integration/docker-compose.client.yml](https://github.com/mendersoftware/integration/blob/master/docker-compose.client.yml) could you make sure that the file matches that of [upstream](https://github.com/mendersoftware/integration/blob/master/docker-compose.client.yml)? If not, check it out from upstream: ```bash ## Enter the root of your integration repository: #cd /path/to/integration git fetch origin --tags git checkout refs/tags/2.5.0 docker-compose.client.yml ``` ---
