SYNC ERROR

It is not possible to make the synchronization of my zotero. I receive this message:
[JavaScript Error: "stream.zotero.org:443 uses an invalid security certificate.

The certificate is not trusted because the issuer certificate is unknown.
The server might not be sending the appropriate intermediate certificates.
An additional root certificate may need to be imported.

Error code: SEC_ERROR_UNKNOWN_ISSUER
"]

[JavaScript Error: "The connection was refused when attempting to contact wss://stream.zotero.org/."]

  • Dear fcheslack,

    I try to make this operation that is mentionned in your link but I didn't find the certificate in firefox... Could you help me?

  • You'll need to follow the steps in the linked page or get someone to help you with that — the instructions are quite precise, and there's not really much more we can add. If there's a specific line that you're misunderstanding, let us know.
