On my Minecraft, Linux Version, whenever I try to login to the launcher, I get an error.
Sorry, but we couldn't connect to our servers. ( IllegalStateException: ).

This error message appears when Minecraft cannot connect to the internet. Check your network connection and your firewall/antivirus settings.
It can also sometimes happen when the Mojang servers are offline. In that case you just have to wait a few minutes and then try again.

Then look at the differences between the two. Like network connection, firewall, etc. Oct 11, 2017 at 23:19
