When I try to set up the Image Server as a https/webdav, I get the following message:
WebDAV Test Failed - An error occurred while trying to upload to your WebDAV server: WebDAV: Could not dispatch request: Server certificate verification failed: issuer is not trusted
Yet I have a valid letsencrypt certificate on the server, that is recognized by most servers.
Besides, even if it was a self-signed certificate, there should be an option in GarageSale to accept the certificate and proceed.
How can I get past this problem?
