</span>Same version of Chromium is working fine on a Raspberry Pi 3 on my lab<br>
bench, without RTC, with NTP, so there must be something in your<br>
environment causing problem.<br>
<br>
There are many possible causes; my guess about clock was just the first one.<br>
<br>
Dig deeper into the message; see if you can elicit further detail from<br>
Chromium.<br>
<br>
You might also try using "wget" to reproduce the error in a Terminal<br>
window, e.g.<br>
<br>
$ wget <a href="https://google.com/" rel="noreferrer" target="_blank">https://google.com/</a><br>
<br>
This may give more detail as to the reason for the protocol error.<br>
<br>
So find a URL that causes the error in Chromium, then copy and paste<br>
the URL for use by wget.<br></blockquote><div><br></div><div>I'm not sure how to get details of the ERR_SSL_PROTOCOL_ERROR message.<br><br>Certainly <a href="https://www.google.com">https://www.google.com</a> and <a href="https://www.youtube.com">https://www.youtube.com</a> etc load fine in other browsers like wget, lynx, etc.<br><br>(On this/these RPi3's the problem is unique to chromium-browser 56.0.2924.84-0ubuntu0.14.04.1.1000)<br><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">As far as OpenSSL is concerned, both wget and Chromium are callers;<br>

<span class="gmail-">> 174870 to see if others hopefully have ideas?<br>
<br>
</span>It does not seem likely to be unique to Raspberry Pi 3, so you might<br>
widen your engagement to OpenSSL and Chromium supporting sites.<br></blockquote><div><br></div><div>Agreed 100%</div></div></div></div>
