Failed to save authentication key file

[bbros-dev]

I have a subscription with 5 subdomains set, and use the provided key in the following command. Running the following as sudo succeeds. However, run as the ordinary user:

tunnelto set-auth --key <redacted>

Produces this error report:

name = 'tunnelto'

I'm having trouble working out the folder and file that are being written to.

[agrinman]

It tries to create a .tunnelto/ in your home directory (i.e run ls ~/.tunnelto/)

[agrinman]

Thanks for the error report, it shouldn't panic -- it should error in friendly way :)

[bbros-dev]

OK, could you consider prioritizing the XDG convention of using location ~/.config/tunnelto/. Then, if ~/.config/ does not exist and XDG_* are not set, fallback to ~/.tunnelto/ ?

[Siilwyn]

Would be great indeed!

Can use dirs::config_dir or dirs::data_dir for that. Would you accept a PR for this @agrinman?

[agrinman]

hi sorry, missed this! yes a PR for this would be great!

[Siilwyn]

Ah it seems I can't use it without paying unless I spin up my own server, not sure if I will pick this up. So for anybody else, feel free to do so.
