Error connecting to connector - “ERR_CONNECTION_REFUSED, TIMEOUT, DENIED

When making a connection to a computer/server or an internal website, the first step is to make your machine able to connect with the connector that is installed in your environment. When you see the above error screen or a message saying ERR_CONNECTION_REFUSED, TIMEOUT or DENIED, it means that there is a blockage between your machine and the connector. Follow the guidelines below to try to resolve this issue.

1. Access the machine where the connector is installed and enter the command below. The status of the 4 containers must be “Up” as shown in the print below.

docker ps -a

2. There may be some firewall rule that is blocking the connection between your machine and the machine where the connector is installed.

If it is an external firewall problem, in the website below, you can check whether the port you use is open or not, if it is closed, you need to open it in the external firewall.

If it is an internal firewall problem, you must contact your firewall administrator to validate if there is any blocking on the port you use or any other specific rule that prevents the connection between your machine and the connector machine.

3. Perform a TELNET from your machine to the machine where the connector is installed. On your machine, type the command below.

telnet (IP or name of the machine where the connector is installed) (Port)

An example of a successful TELNET follows.

4. If you are doing a NAT for the port that will be used to connect to the connector, the NAT configuration may be wrong, that is, the NAT is pointing to another service that is not VaultOne.
