I’ve realized that the issue was not the difficulty.
If the difficulty is less than 36 I get the correct message:
Error: certificates peer error: authorization claim error: difficulty must be greater than: 35
What returned me the
Error: file or directory not found... error message was to point my identity dir (i.e. using
--identity-dir flag) to a path in my home directory using
~ shorthand. If I use the full extended absolute path
/home/username/... then it works and I see the correct message.
The thing is that the application doesn’t handle the
~ for a reason that I don’t know now.
I create a ticket in our issue tracker for being attended in the future as it isn’t a high priority.
This is what I found, but as far as I understand in your comments, you’re not using the
--identity-directory flag and the error message shows the absolute path without the
~ shorthand so I don’t know again what could be wrong in your environment.
Nonetheless, it’s certain that you need an identity with more than 35 of difficulty.
Please report back once you get an identity with more than 35 of difficulty and you try to authorize it despite if you succeed or not.
