Joplin Cloud Sync not working

Operating system

Windows

Joplin version

3.5.13

Desktop version info

Desktop app

Sync target

Joplin Cloud

What issue do you have?

After selecting Joplin Cloud as sync target in the desktop app, I clicked on the Authorise button, which takes me to a webpage where I can succesfully authorise the app. Now when I go back to the app there's the following error message:

You were unable to connect to Joplin Cloud. Please check your credentials and try again. Error:request to https://api.joplincloud.com/api/sessions failed, reason: self signed certificate in certificate chain

Do you happen to be using a work computer? Some network policies may prevent it from working

I am on a work computer yes. I'll check with IT, thanks.
