Upgrade StorageZotero 9.0.6 — HTTP 0 GET errors with cPanel WebDAV
I'm trying to use a Bluehost/cPanel Web Disk account for Zotero WebDAV file syncing.
Zotero 9.0.6 (ARM64), macOS 26.6.2.
Zotero repeatedly reports:
Your WebDAV server returned an HTTP 0 error for a GET request
for files under:
/zotero/[item].prop
and eventually reports:
The server could not be reached.
I've tested the WebDAV server independently from the same Mac:
TCP connection to port 2078 succeeds
TLS connection succeeds and certificate verification passes
Unauthenticated request returns HTTP 401 as expected
Authenticated PROPFIND returns HTTP 207 Multi-Status
Authenticated PUT via curl succeeds and creates a file
So the server is reachable and accepts authenticated WebDAV requests outside Zotero.
Debug ID: D1826068950
Is there something in Zotero 9's handling of cPanel WebDAV/Basic authentication that could explain the HTTP 0 GET failures?

But "HTTP 0" would be the connection being blocked or interrupted, so it's likely some sort of issue with the server. You'll likely need to check the server logs.
