To fix common Mail.ru Agent connection errors, you must primarily address incorrect authentication credentials, security/firewall blockages, and misconfigured server ports. 1. Resolve Authentication and Login Failures
Account verification issues are the most frequent cause of connection drops.
Generate an App Password: If you have two-factor authentication (2FA) enabled on your Mail.ru account, your regular password will not work. You must log into the Mail.ru web interface, navigate to your security settings, and generate a unique app-specific password for the Agent client.
Check VK ID Settings: If you log in via VK ID and experience an infinite loading loop or connection failure, ensure your default web browser (such as Chrome, Edge, or Safari) is not blocking pop-up windows. These are often required to pass authentication handshakes.
Reset if Compromised: If the client explicitly states your password is wrong but you are certain it is correct, your account security may be compromised. Use the official Mail.ru Password Recovery Page to reset it immediately. 2. Configure Firewall and Network Rules
Local security software frequently misidentifies Mail.ru Agent traffic as suspicious and restricts its access.
Open Port 2042: Mail.ru Agent utilizes the proprietary MRIM protocol to communicate. Ensure your Windows Firewall or third-party antivirus allows traffic through Port 2042.
Whitelist the Executable: Add magent.exe to the exclusions list of your antivirus or network monitoring software.
SSL/TLS Interception: If your security software performs SSL/TLS deep packet inspection, it will break the Agent’s secure connection. Change your antivirus configuration to “Allow certificate replacement” or disable HTTPS scanning specifically for Mail.ru domains. 3. Verify IMAP/SMTP Mail Client Settings
If you are using Mail.ru Agent features that sync with your inbox via external mail tools (like Outlook or eM Client), check the protocol criteria: IMAP (Incoming) SMTP (Outgoing) Server Address imap.mail.ru smtp.mail.ru Port 993 465 or 587 Encryption SSL/TLS or STARTTLS 4.
