can you ping from one server to the other? Are you using IPs or hostnames?

[URGENT] - SQLSTATE[HY000] [2002] No route to host
I have 2 servers. 1 is serving the websites and the other is the MySQL server.
I'm hosting them on Vultr. Everything was going well, uptime was 100% for the past few months, and suddenly, without changing anything on the server I've got this error message from the Webserver: SQLSTATE[HY000] [2002] No route to host
I'm using Laravel 5.5. I've checked the IP addresses of the servers but they haven't changed.
Does anyone have a clue what could be the problem?

What solved the issue for me was:
sysctl net.ipv4.conf.all.forwarding=1
sudo iptables -P FORWARD ACCEPT
