    So a few weeks ago, our WP Mail SMTP client told us that our account couldn’t be authenticated. I’ve tried updating the plugins, re logging in, updating php, nothing seems to work. Has anyone had similar issues?

    Versions:
    WordPress: 6.0
    WordPress MS: No
    PHP: 7.4.29
    WP Mail SMTP: 3.5.1

    Params:
    Mailer: smtp
    Constants: No
    ErrorInfo: SMTP Error: Could not authenticate.
    Host: smtpout.secureserver.net
    Port: 80
    SMTPSecure: string(0) “”
    SMTPAutoTLS: bool(false)
    SMTPAuth: bool(true)

    Server:
    OpenSSL: OpenSSL 1.1.1o 3 May 2022

    Debug:
    Email Source: WP Mail SMTP
    Mailer: Other SMTP
    SMTP Error: Could not authenticate.

    Hi @saxsmith,

    Thanks for reaching out!

    According to your error log, most probably your server’s Firewall or ModSecurity rules are blocking your SMTP connection requests.

    Could you please get in touch with your hosting support with the full error log and they should be able to assist you accordingly.

    I hope this helps. Thanks!
