Troubleshooting no connection

How to troubleshoot the network connection on your VPS

Common issues

At Crunchbits, we have a few most common issues that lead to no connection on your VPS/dedicated server:

Incorrect network configuration

The most common one is incorrect network configuration, or incorrect formatting.

We have a very extensive section of tutorials that explains the correct configuration, as well as formatting, which can be found here: Manual configuration

Random Unexplained Issues

The second most common cause of connection loss stems from unexpected system issues, which can range from installed software conflicts to corrupted system files or kernel panics. The vast majority of those can be fixed with a simple reboot from the respective management panels. [Metal / Virt]

Incorrect interface name

The last most common issue that our clients encounter is partway due to incorrect configuration.

You can check the correct interface name via the following command:

ip link show

And in the output looking for an interface that has state UP:

2: ens18: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether HIDDENMACADDRESS brd ff:ff:ff:ff:ff:ff
    altname enp0s18

Then exchanging the interface name within your network configuration to the one from the command above, and restarting the networking process, or rebooting your service.
