Error: A timeout of 5 minutes is exceeded. Please ensure your EC2 instance has access to the Internet.

I’m sure that this is a configuration issue on my end but I’m not sure what the problem is.

I made the inbound traffic rules wide open to help troubleshoot this:

Inbound rules
Type | Protocol | Port range | Source | Description - optional
-- | -- | -- | -- | --
All traffic | All | All | 0.0.0.0/0 | wide open for testing
All traffic | All | All | ::/0 | wide open for testing

Outbound rules
Port range | Protocol | Destination | Security groups
-- | -- | -- | --
443 | TCP | 0.0.0.0/0 | GitHubActionSelfHostedRunner

I’m able to SSH onto the EC2 instance that gets spun up – any other ideas on how to test?

If you run it in the private subnet, please make sure you use NAT Gateway with this subnet, so your instance with private IP has access to the Internet and can pull the jobs from GitHub. Otherwise, the instance with the private IP won’t be able to connect to the internet.

@machulav you were right - worked once I attached a NAT gateway!

Hey @davinchia,

The instance is currently running in a private VPC/subnet with a private IP. Does the instance need a public IP?

If you run it in the private subnet, please make sure you use NAT Gateway with this subnet, so your instance with private IP has access to the Internet and can pull the jobs from GitHub. Otherwise, the instance with the private IP won’t be able to connect to the internet.

I hope it helps!
