I just opened my website today and saw that “Error 521” web server is down! Also I’ve been using digital ocean for the past 5 months with cloudflare and haven’t seen such an error? So any help would be much appreciated.

×Thanks to you! I just somehow found out that I need to reboot my droplet. For anyone who is facing such an issue try rebooting your droplet.
To reboot a server from the command line, run:
Question
sudo shutdown -r now
To restart Apache, run:
sudo service apache2 restart
Everything is working fine! BTW DigitalOcean support was not helpfull at all! They cant even suggest a thing apart from repeating one thing! “its not our problem”
I use DigitalOcean for 8 days, and I meet this issue 4th time, I usually doing shutdown or wait 2 hours, but this time I have same error log, but shutdown and restart isn’t work for me anymore
Can you share us some logs? You can find these in /var/log - perhaps give us the last few lines of the apache2/error.log if you run apache. Please let us know some more information about the software your server is running and your stack. Thanks
my apache2/error.log is showing something like this
