Error 5 can sometimes occur when you attempt to connect to a remote session or a server, indicating that the host name does not exist or is not accessible. It is generally a connection problem and can be resolved using the tips outlined in this guide.
Overview
Error 5 can indicate that your connection entry cannot find the hostname or IP address you are trying to connect to. It is a common error that occurs when you attempt to establish a secure connection with a remote server. If you get this error, it most likely means that your remote settings have been misconfigured. To resolve the issue, you will need to determine what settings need to be adjusted in order to re-establish the connection.
Step-by-Step Solution
Below are the steps to take in order to resolve the connection issue caused by Error 5.
Verify the hostname or IP address is accessible from your current location. Try typing the hostname in your package manager console and see if you can get a response.
If the hostname exists, check the port number and protocol you are using to connect. Make sure the port number is open on both the client and the server, and ensure the protocol is allowed in your firewall.
Double-check the username and password you are using to connect to the server. Make sure it is correct and has exact match to the server.
Verify that the server is configured to allow or respond to connections from the client's IP address. It should be accessible even if the client's IP address is tied to a dynamic IP address.
Ensure the server is reachable from the public network. If the server is behind a NAT or firewall, adjust the settings to allow incoming connections.
Restart the connection one more time and try connecting to the server again. This will reset the connection and should solve the issue.
