Unsecured Connection error message

Hi and welcome,

good to ask this before blindly pressing connect. In general it is indeed not a good idea to send credentials via an unencrypted connection.

In this specific case it is a different situation, though. Neither are there credentials nor is the connection leaving your computer. The message is due to the fact that Cryptomator used to use a WebDAV connection from your Finder to Cryptomator (which is a loopback connection since both applications run on the same machine).

Sadly, it is not possible to create a (valid) SSL certificate for “localhost”. I.e. there is nothing we can do about this error, which usually makes a lot of sense when connecting to remote hosts via public networks.

If you’re interested in more details, this has already been discussed:


If you feel annoyed by this warning, you might want to use FUSE instead of WebDAV to access your vault.

Regarding the error message, I’d need to see the log file for details. But before we dive into that, I’d suggest to simply use FUSE.
