Ssl3_read_bytes:sslv3 alert handshake failure

I have a group of 12 sites that are different locations of company. I have previously had all 12 of these sites running in MainWP.

I’ve been updating the site designs, but I’ve been using a separate temp website to build the new design then I move it over to the live site location via Updraft.

However when I move the new design over (full file/db move) MainWP will no longer work. The connection is lost and when I try to reconnect I get the following error:

Error message: error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure

This has happened on every site I’ve done this to. I’ve tried turning off the SSL option on the WPMain dashboard but no joy. It’s using Let’s Encrypt on SiteGround.

Any ideas what causes this and how I may fix it?

Can you please post the community system report from your MainWP Dashboard for review? The report is located in your Dashboard under Status → Server, on the top right of the page.

Hi Chris,

the report looks ok. I can’t see anything unusual.

Are you able to try to reinstall the SSL cert of the child site and see if that helps?

I will try that and see what happens. I will report back when I can do that.

Deleted SSL for child site, purged cache, added SSL back. Same error:
HTTP error - error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure

Besides all the plugins that are installed and in my opinion not used by MainWP (you should use a separate (sub)domain for your MainWP Dashboard), I’ve seen these errors when the OpenSSL setup on one of the servers is incorrect. If it’s using protocols that are too old, it can’t communicate with newer servers that stopped supporting these deprecated/abandoned protocols. If the child site is moved and introducing the issue, it’s probably the server where your Dashboard is running on.

You can test the status on SSL Server Test (Powered by Qualys SSL Labs)

Hi Jos, ran it through the suggested site. It received an “A” rating with TLS 1.3.

And just to be sure: what’s the result when you test the child site?

Yes, same result. All of these sites are in the Same SiteGround account and I would assume (but maybe not) on the same server.

This is my process: www.somesubsite. com is working, child theme is working. MainWP connection working.
Using www.sometempdomainassignedbySG. com I build the new site
I move the site from said temp domain to www.somesubsite. com using Updraft (pro version)
Site no longer connected and cannot reconnect in MainWP dashboard.

Then I’m out of ideas. Did you contact Siteground? It’s mostly hosting related, so hopefully they know what the issue is and how you can solve it.


I would agree with Jos, it may be best to check with the SG support and have them verify that everything is set correctly on their side.


OK, thanks all. Will contact SG.
