It seems that you're using an outdated browser. Some things may not work as they should (or don't work at all).
We suggest you upgrade newer and better browser like: Chrome, Firefox, Internet Explorer or Opera

The game doesn't use the internet to connect for the Daily Challenges :( on Linux Fedora 33. Keeps giving error: Failed There is a problem connecting to the server..etc.etc. Please Help!
God Bless!

Can confirm. Never has worked for me. Seems to be an issue specifically with the Linux GOG version. At some point they added a note to the store page:

> Additional Notes: Galaxy client is required to access Daily Runs and Streaming features

But the Galaxy client does not exist for Linux.
