    Hi there,

    until a few days ago everything was working properly, then I have noticed that emails are not sent and I get this error in Plugin WP Mail SMTP by WPForms:

    Versions:
    WordPress: 5.7.2
    WordPress MS: No
    PHP: 7.4.22
    WP Mail SMTP: 3.0.3
    
    Params:
    Mailer: sendinblue
    Constants: No
    API Key: Yes
    
    Debug:
    Email Source: WP Mail SMTP
    Mailer: Sendinblue
    [503] Server error: <code>POST https://api.sendinblue.com/v3/smtp/email</code> resulted in a <code>503 Service Unavailable</code> response:
    upstream connect error or disconnect/reset before headers. reset reason: connection failure

    Can someone help?
