I’m not sure where to start troubleshooting this, but to make a long story short, I have 2 modx sites hosted on a cloud server I manage. One site works fine, the other site times out on any request to the site’s url, including the manager, and I don’t have any idea why. These were both working sites for months, and this just started happening after not visiting either site for a while. I can ssh to the server and do anytthing I need to that way, but I don’t know where to start looking for issues when I’m not aware of any changes that led to the one site being down.
The server is on Ubuntu 16.04 LTS, running apache, and the latest version of modx on both sites as far as I remember.
