Hello, when I use my NAS to synchronize Zotero, the HTTPS link shows that it cannot establish a secure connection, but HTTP can synchronize. (Addition: Only HTTPS can be used in iPad, which prevents me from synchronizing.)

However, I have successfully mounted the NAS using WebDAV in RaiDrive, and it is at this point that I am using the HTTPS link.

So I would like to ask how to resolve this issue, thanks.
