curl error 52 when trying to setup fresh install

    Hi all – i have a self hosted wordpress installation and im trying to install jetpack and link it to my www.remarpro.com account

    Upon installing the plugin, the next step is to ‘set up jetpack’ on the jetpack plugin page.

    Clicking that goes to do what it needs, but shortly comes up with a message “cURL error 52: Empty reply from server”

    Ive tried for days to determine where this error comes from (i am a senior linux admin, and have been trying to trace code, do various network test and http config to see where this is occuring) but to no avail…

    i can replicate it on the command line if i disable sslv3 ssl protocol in httpd config

    curl www.mydomain.com:443
curl: (52) Empty reply from server

    and then re-enabling sslv3 (which is what i have enabled normally)

    curl www.mydomain.com:443
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

<address>Apache/2.2.29 (CentOS) Server at mydomain.com Port 443</address>
</body></html>

    I dont think its on my end – as i can successfully do a curl lookup on my domain, or IP and not get the error (as i have sslv3 still enabled)

    Im trying to see if its an issue on jetpack’s side, or www.remarpro.com’s side – or mine…

    But im stuck now because i cant compete the setup

    ive tried disabling all plugins, (and doing a fresh install on jetpack) – and still get this error…

    Has anyone else got this error, and/or worked out a solution? – ive been trying to diagnose/debug/research this for the last 3 days.

    cheers

    further information:
    site health is 100% clear, jetpack debug reports a-ok

    the only error we see is the curl 52 error, and then on the jetpack debug page it says cannot validate security token

    all the curl tests (demo.hello etc) i have seen online all give me the correct output and xmlrpc seems to be functioning as expected.

    a fresh install of wordpress and jetpack (alone) – still gives me this error (curl 52)

    Hey @phd05,

    I’m gathering via contextual clues that you don’t want your URL posted here on the forums, is that right? Can you please contact us at the form I’ve linked here? Make sure to link this thread in your ticket.

    We’ll need to know your site’s URL to be able to troubleshoot. Feel free to send us that Site Health output as well.

    Thanks!

    The url is https://www.dizzidecalz.com.au

    I had also submitted info via that form previously about 4 days ago – but had no reply just yet from there as I assumed because I’m using the free plan there is no support apart from here – but without being able to install and test it I can’t commit to a plan if it’s not going to work

    as frustrating as this issue is – i have moved VPS’s and my site is running on a new server – and its working now.. i think it may have been related to SNI (i have multiple ssl sites running off that vps with difference certificates)

    I really dont know 100% – but its working on the new server and i can connect it successfully.
