files not syncing / wss://stream.zotero.org not reachable (2001635380)

PWE
I'm having issues syncing files from external to a PC. Adding them locally and syncing them to the cloud is not a problem.

May this be a firewall issue when connecting to wss://stream.zotero.org?

    I'm behind the same proxy and found that it indeed works using Zotero 6.

    It looks like the implemention changed slightly.

    How can I assist in debugging this issue?

    BTW: Disabling WebSockets does not help. The error message is:

    [JavaScript Error: "S3 returned 0 for 2228042/7QVTDDUC -- retrying download" {file: "chrome://zotero/content/xpcom/storage/zfs.js" line: 177}]

    We can look at a Debug ID, but Zotero's network stack is just Firefox's. Zotero 6 was based on Firefox 60. Zotero 7 is based on Firefox 115. Most likely you'll need to debug this on your end. If you're getting as far as the above error, Zotero's network requests are working for you generally and it's just requests to Amazon S3 that are being blocked.

    (As I've explained before, the WebSockets connection is totally irrelevant.)
