When connecting to the IMAP, POP3, or SMTP mail servers, you may come across the error "Failed to Create a Connection Socket". This message means that the connection to the mail server failed and could not be established. Here are a few common things to check when encrountered with this error.

• Make sure the host and port are correct: An incorrect hostname or port may cause this error and prevent the connection


• Make sure the port is not blocked: If the port you are trying to use is being blocked, this can block the connection


• Make sure there are no anti-virus software or firewalls that are blocking the connection: Antivirus software or third party firewalls on the user’s machine can sometimes block connections to certain IPs
