update connection to facebook/twitter

Your site doesn’t seem to be properly connected to WordPress.com at the moment. Could you try the following:

1. Go the Jetpack menu in your dashboard
2. Scroll down to find the Connections area.
3. Click the “Manage site connection” link where your site is listed.
4. Click the red Disconnect button.
5. Click on the Connect button to connect your site to WordPress.com again.

Once you’ve done so, try going to this page to reset your connection to Facebook and Twitter:
https://wordpress.com/sharing/

Let me know how it goes!

Did that and don′t get messages anymore, so it seems to work. Haven′t published a post yet…

Thanks

Hello Jeremy,
After it worked for 1 week, I got the same issue again and already tried to reconnect to wordpress.com, this time without success. Do you know what causes this issue? It′s really annoying as it appears in random periods of time and I don′t know how to fix it.
I did update some plugins yesterday but not jetpack?!

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 to send us the debug results privately. It’s best not to post this information on public forums, as it contains private details about your site.

That should give us some extra details about what may be happening on your site.

Thanks!

Thanks Jeremy,

I did not take any further action and today I don′t get the messages anymore. In case this will appear again in the future, I will send the report as mail to the support.
Maybe my provider blocked some features due to the WannaCry-attack, but I wasn′t informed about that and it′s only a guess.
