Subject: Cannot Decode response from Gmail on Authenticate to SMTP via OAUTH2 Date: 2022-08-26 14:01:46 From: yurienricardo Source: cannot-decode-response-gmail-authenticate-smtp-via-oauth2 ---------------------------------------------------------------------- Hi, we are able to connect to **smtp.gmail.com** via Connect("smtp.gmail.com", 465, ComponentPro.Net.SslSecurityMode.Implicit) and is succesfull. Issue is when Authenticating via **AuthenticateAsync(gmailToken, SmtpAuthenticationMethod.OAuth20)** using token that is enabled and tested on other apps. We receive the exception with message **Cannot Decode response g6-20020a05660226c600b006814fd71117sm1102768ioo.12 - gsmtp (501).** Any help will be appreciated.
