      <p>Hello! please send traces and 2 more screens from 2 other tabs of certificate, shown on your screen.</p>
      <p>also:</p>
      <ul>
      <li>do you use a Virtual PC?</li>
      <li>is it possible that you had deleted our certificate from trusted root?</li>
      </ul>
      <p>(we cannot reproduce it in test lab)</p>
      <p></p>

        <p>Hello! <a href="https://drive.google.com/file/d/1rbZWb2qmkf1FU53ohGGJdXMaLnJuhioG/view?usp=share_link" target="_blank" rel="noopener">Traces</a> added as requested also <a href="https://i.ibb.co/tBmCzND/01.png" target="_blank" rel="noopener">screenshot 1</a> and <a href="https://i.ibb.co/3kYz9HP/02.png" target="_blank" rel="noopener">Screenshot 2</a> added. Lookslike the certificate (imap.gmail.com) does not have a valid digital signature. Yes i use always Virtual PC on test. No i didnt deleted any certificate from system.</p>

          <p>Can you try reproduce it, while pausing AV on your host PC? BTW, is it Kaspersky too?</p>

              <p>This is the key. Such scenarios are abnormal, such "double" protection can cause that kind of issues. </p>
              <p>So it's not a bug. </p>

                <p>@nexon, I think, some exceptions can be set. For example, add virtualization app into trusted group, and in iapp's rules choose "do not check encrypted traffic"</p>

                  <p>@dmitriy-pisarets I never gave an exception so I didn't think it could cause a problem.. But i will tweak it.</p>
