Can't connect Inbox (Outlook for Mac) with Hubspot

This is the error I get when trying to connect my Exchange Inbox in Outlook for Mac with Hubspot.
“HubSpot konnte leider keine Verknüpfung mit Ihrem E-Mail-Konto herstellen.”

Unfortunately, HubSpot was unable to connect to your email account.

When I click on the link the following message appears

But I am connected to the Internet

Any idea what I could do to fix it?

Thanks

Hey, @AndreasN :waving_hand: You might want to file an email support ticket for this one. It’s tough to troubleshoot these cases when they are happening locally. It could be an issue with your machine or your network. But without more access, it’s tough to be certain. Hey @gabriel-nextiny @MatthiasWeber do you know of any additional troubleshooting steps @AndreasN might try?

Thank you very much for taking a look! — Jaycee
