Error in resolving matlink.fr is badly handled

I WON'T ANSWER IF YOU DON'T PROVIDE SUCH DETAILS. COPY-PASTING IS NOT ENOUGH, I'M NOT A JEDI (YET).

Please provide those informations:

[Windows 7 x64 ] Operating System (ie Ubuntu 16.04)
[3.6.5 ] Python version when running gplaycli (should be 3+)
[3.25] GPlayCli version via gplaycli -v
[pip install gplaycli] The way you installed gplaycli: git clone, git clone and setup.py, pip install gplaycli, apt install gplaycli, ...
[not sure, but I didn't configure my own credentials] The authentication method: (own) credentials or (own) token.

Running gplaycli -d someappid failed with the following errors:

This gives the user no idea what the problem is. With -v it gives a hint:

[INFO] GPlayCli version 3.25 [Python3.6.5]
[INFO] Configuration file is C:\Users\Rey/.config/gplaycli/gplaycli.conf
[INFO] Device is bacon
[ERROR] cache file does not exists or is corrupted
[INFO] Retrieving token ...
[INFO] Token URL is https://matlink.fr/token/email/gsfid/bacon

(then the same errors as above)

(My system was unable to resolve matlink.fr temporarily for some reason.) It would be nice to clearly report something like Unable to download URL "https://matlink.fr/token/email/gsfid/bacon" -> Failed to resolve "matlink.fr"
