hi guys i have my onpremise Openvidu 2.15 deployed on aws using cloud formation script (dockerized). I would like to create a full load test and try how many users i can support on this kind of instance and some other stuff. Navigating on github i found this: > **[OpenVidu/openvidu-loadtest](https://github.com/OpenVidu/openvidu-loadtest)** > > OpenVidu load testing environment. Contribute to OpenVidu/openvidu-loadtest development by creating an account on GitHub. I just install all packages (java 11, node, maven) and test starting correctly, but when workers try to connecto to my openvidu instances i receive an error on certificates (i use let’s encrypt). My Worker run on default port 5000. Load test (mvn spring:boot:run) launched on the same machine of worker. My Load Test conf file is: OPENVIDU\_URL=https://dev-openvidu.xxxxxxxx.com OPENVIDU\_SECRET=dhKy#sssssssssssss WORKER\_URL\_LIST=http://localhost:5000 please see the picture Load Console plus Worker Console on top right ![immagine](https://global.discourse-cdn.com/free1/uploads/openvidu/original/2X/e/e91179837d53ee1a1ff4fb0f669d90e28ba74023.png) Please could you help me to find the issue? thanks in advanced ---

Hello, As you can read on the top of the README, this project is under development and bugs can appear. However, i am testing an OpenVidu 2.16 environment deployed on premises with letsencrypt certificate and everything is working as expected. Have you checked that you have access to your stack with any other app? ---

hi csantos and thanks for your fast reply. yes, all other applications works correctly. did you deployed Openvidu with cloud formation (yaml file) on aws? i use openvidu 2.15, maybe issue regarding openvidu version? when i launch a test where i can found the call (like curl [https://openvidutest.blabla.com](https://openvidutest.blabla.com)) that cause an error? there’s a log file or something else? thanks in advanced ---

Test with 2.16 version as maybe there are some incompatibility with 2.15. ---
