Server is not responding - WordPress

April 29, 2016 1.1k views
WordPress Server Optimization

We have a simple WordPress droplet running as our helpcenter.
It's a 4 GB Memory / 30 GB Disk / SFO1.

It's constantly showing error 502, server not responding. But I can access it via SSH, FTP etc.

It was working well and I didnt changed anything on WP instalattion.

Top and Htop commands shows that we have plenty of memory and CPU %.

  • ASB, let me know if I can send you any additional info.

  • Still happening even after adding more ram and cpu. I don't know what to do. Can anyone help me out in this one?
