### 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](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
