Hi everyone, I am totally new in genieacs. This is my first time to install genieacs. I have a question about genieacs UI. # From [genieacs/README.md at master · genieacs/genieacs · GitHub](https://github.com/genieacs/genieacs/blob/master/README.md) genieacs-ui This serves the web based user interface. It listens on port 3000 by default. You must pass --ui-jwt-secret argument to supply the secret key used for signing browser cookies: # genieacs-ui --ui-jwt-secret secret The UI has plenty of configuration options. When you open GenieACS’s UI in a browser you’ll be greeted with a database initialization wizard to help you populate some initial configuration. My question is how to get the secret key? And how to pass it to browser? Many thanks! ---

Hi, the UI\_JWT\_SECRET must be passed to the genieacs-ui process as a environment variable, so if you configured the process to run as a systemd service, you must add this line to the environment file configured: ```auto GENIEACS_UI_JWT_SECRET= ``` ---

Hi Lavira, Many many thanks for your answer. 🙂 Now my environment variable in /opt/genieacs/genieacs.env is GENIEACS\_UI\_JWT\_SECRET=secret Do you mean I should change it to GENIEACS\_UI\_JWT\_SECRET=\ ? Where should I get this random string? Thanks for your help! Vincent ---

Hi Lavira, Can you help to check my steps: 1. I try to online create a JWR\_SECRET from [https://www.javainuse.com/jwtgenerator](https://www.javainuse.com/jwtgenerator) 2. Then I get the key as eyJhbGciOiJIUzI1NiJ9.eyJVc2VybmFtZSI6IkphdmFJblVzZSJ9.Cak4ou7W9ndNFTc-4JxXQcBw3jbhxa7ve34JHFHh8K0 3. Then I update /opt/genieacs/genieacs.env as GENIEACS\_UI\_JWT\_SECRET=eyJhbGciOiJIUzI1NiJ9.eyJVc2VybmFtZSI6IkphdmFJblVzZSJ9.Cak4ou7W9ndNFTc-4JxXQcBw3jbhxa7ve34JHFHh8K0 4. Restart genieacs-ui service 5. From browser, input http://\:3000 But still get “This site can’t be reached” Thanks! ---

In order for the UI to work, you also need the other UI related config in that genieacs.env file: ```auto GENIEACS_UI_INTERFACE=0.0.0.0 GENIEACS_UI_PORT=3000 ``` do you have these? If yes, what’s the output of the following command? ```auto systemctl status genieacs-ui.service ``` ---

Hi, The logs indicate clearly that the service can’t connect to the mongo database. It seems you are missing a line, in the genieacs.env file, like: ```auto GENIEACS_MONGODB_CONNECTION_URL=mongodb://user:password@127.0.0.1/genieacs ``` Since you don’t mention this, the default connction url is mongodb://127.0.0.1/genieacs and I think you don’t have mongodb running (`systemctl start mongodb`) or you don’t allow the connection. If you forgot to install it, here you can find [install instructions](https://docs.mongodb.com/manual/administration/install-on-linux/). ---

Thank you very much Lavira! It is very helpful. I have installed mongodb, I am configuring it now. Vincent ---

Many thanks Lavira! After configuring mongodb, genieacs-ui works well. I use genieacs-sim to do some basic test. From “Devices”, I can find the simulator. 🙂
