As mentioned in a previous blog post, my current project is deployed using Docker. However, during a recent login to the server, a strange phenomenon occurred: all the containers in Docker would restart from time to time. Also, every time I logged in to check the Docker status, it would show that the containers had just started (Up 15 seconds). After several investigations, I finally identified that the restart issue was related to SSH login. Every time I logged in via SSH, the containers would restart.

After three months of hard work, the SSL certificate of my RSS aggregator finally expired. The auto-renew script failed to renew it — this happened a couple of times, I need to login into the web panel and renew it manually every three months. Unfortunately, the web panel malfunctioned this time either. After an epic battle with cert-bot, Nginx, and even the web panel I used, I finally gave up and decided to switch to another self-hosting solution.
