How to fix the Load Balancer’s connectivity issue in DigitalOcean?

While trying to create a connection with the DigitalOcean droplet using the Load Balancer, we may sometimes experience a connectivity issue. We can troubleshoot the issue with these steps:

• Know the Load balancer’s status.
• Test the connection between the Load balancer and the public network.
• Verify the Load balancer’s DNS settings.

Let’s look into the details of each step now.

Know the Load balancer’s status

1. Go to the DigitalOcean Control Panel.

2. Select Networking.

3. Now click the Load Balancers button. Now we can see all the Load Balancers. We’ve to choose the required one from them.

The Droplet tab of the load balancer shows a list of the Droplets that are linked to it. The status column shows the strength of the link between the Droplets and the load balancer. If the droplet is down even if it is shown as connected to the load balancer, there may be a problem with its internal network configuration.

So make sure the Droplets are sound and working.

Test the connection between the Load balancer and the public network

We can use the command ping to test the connection between the Load balancer and the internet. We’ve to use the below code:

ping <load-balancer-ip-address>

Ping outputs the amount of data transmitted to the load balancer and the time it takes for the data to arrive. However, if it is unreachable, it will show a time-out error as given below:

We can check the droplet also in this way. If there is no issue, then we can tell the issue is caused by the Load balancer. If that’s the case, then we can fix the issue by deleting the Load balancer and replacing it with a new one.

Verify the Load balancer’s DNS settings

We must configure an A record with the DNS provider to direct the hostname to the load balancer’s IP address if we are trying to access the load balancer using a hostname. To make sure about the A record, we need to use the dig on a terminal to get the A records set up on the domain.

dig <use-hostname> A

We must add an A record to the hostname’s DNS setup if the ANSWER SECTION of the output doesn’t already contain one pointing at the IP address of the load balancer. We can use the DigitalOcean Control Panel if the DNS provider is DigitalOcean.
