Hello. I have looked for a solution but could not find one.

I am trying to sync zotero standlone with webdev on seafile server. Which sits behind Nginx with HTTPS, the ssl cert was self signed using openssl. I can access the webdav server in chrome and firefox fine, and generation of cert_override.txt in firefox works. Further more zotero in firefox works with the server as well (it successfully syncs, and creating test file in zotero folder).

The problem is even if I place the cert_override.txt into zotero standalone profile directory it does not recognize the ssl exception.
The location I placed cert_override.txt into: (This is default directory zotero creates, and is different from documentation, i wounder if its a bug?)
C:\Users\<user>\AppData\Roaming\Zotero\Zotero\Profiles\<random>.default

The hierarchy of my ssl certificate is ( there are no intermediary certificates, just the one)
<myserver>.duckdns.org

and in the cert_override.txt file it uses same website information

<myserver>.duckdns.org:443

So I am at a loss as to what is wrong. Any help would be appreciated!

P.S zotero standalone version is 4.0.28
