invalid_client error on update to 3.4.1

Could you try to go to the Plugins menu in your dashboard, deactivate and then delete the plugin completely, and then reinstall? It should solve this error.

Let me know how it goes.

Tried that several times – doesn’t work. Get this error:

Jetpack could not contact WordPress.com: register_http_request_failed. This usually means something is incorrectly configured on your web host.
Operation timed out after 15000 milliseconds with 0 bytes received

That seems to be a different error. Can you please use Jetpack’s Debugger module to send us some more information about your site?

1) Go to the Jetpack page in your dashboard.
2) Click on the Debug link appearing at the bottom of the page.
3) Click the link that says “click here to contact Jetpack support.”
4) Fill in the description box and your name and email address.
5) Click the “Contact Support” button.

Thanks!

Can’t connect via debug.

There seems to be a problem with your site’s ability to communicate with Jetpack!

Your site isn’t reaching the Jetpack servers.
Your site isn’t securely reaching the Jetpack servers.
It looks like your site can not communicate properly with Jetpack.
Trouble with Jetpack?

It may be caused by one of these issues, which you can diagnose yourself:

A known issue. Some themes and plugins have known conflicts with Jetpack – check the list. (You can also browse the Jetpack support pages or Jetpack support forum to see if others have experienced and solved the problem.)
An incompatible plugin. Find out by disabling all plugins except Jetpack. If the problem persists, it’s not a plugin issue. If the problem is solved, turn your plugins on one by one until the problem pops up again – there’s the culprit! Let us know, and we’ll try to help.
A theme conflict. If your problem isn’t known or caused by a plugin, try activating Twenty Twelve (the default WordPress theme). If this solves the problem, something in your theme is probably broken – let the theme’s author know.
A problem with your XMLRPC file. Load your XMLRPC file. It should say “XML-RPC server accepts POST requests only.” on a line by itself.
– If it’s not by itself, a theme or plugin is displaying extra characters. Try steps 2 and 3.
– If you get a 404 message, contact your web host. Their security may block XMLRPC.

Not using any of the plugins here: https://jetpack.me/support/getting-started-with-jetpack/known-issues/

XMLRPC is correct

Could you try clicking the link at the bottom of the Debug page to send us the debug test results?

Thanks!

I did – it won’t run the debugger. The error I listed above is what I get when I click on “debug”.

What happens when you click on this link?

You should then see a contact form appear at the bottom of the page:

When I click this link https://i.wpne.ws/aRcs

I get a screenshot with this text in it:
– If it’s not by itself, a theme or plugin is displaying extra characters. Try steps 2 and 3.
– If you get a 404 message, contact your web host. Their security may block XMLRPC.

There’s no contact form when I click Debug. Here is the entire text of the page I get:

Ok, thanks for trying. You seem to be missing a part of the Debug page.

Would you mind contacting us via this form, so we can run some more tests on your site?

Thanks!

Hi – I submitted the form yesterday as requested and haven’t heard anything. Also don’t have a technical report number to follow up with. Do you know the status of my request? Thanks

@denisewithers I’m sorry for the delay. We’re working on a backlog of support requests at this time, and we generally answer in the order received. You should receive a reply soon!

@denisewithers: Thanks for getting in touch! I just replied to your email. I’m going to mark this thread resolved, to avoid crossing our lines of communication.
