Hi @Jyoti_Rajai What are the system requirements.? 1. Is CPU and RAM are doing good? 2. Check your internet, due to the internet slowness we may get this issue. 3. Did you restarted the pmm server? 4. Check the pmm2 server status weather it is healthy or not? docker ps -a ---

Hi @Jyoti_Rajai Seems postgresql DB has some issue, it did not start properly. Can you download the server Diagnostics and check the details. It may help this issue. Can you stop the docker service and restart the Linux server node then try once. ![image](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/8/88f4bbef480d8b0916b1c99b51fc081d316a20cf.png) ---

Why to reboot linux server ? That doesn’t sounds proper. Additionally, what i have found is the docker stores all data in memory instead of given path for volume. ---
