Text version: After completing migration, I can't get access to the game. Every time I click "Microsoft login", something loads for a bit and I get the error that recommends me checking my internet connection.

At the same time, I can login to any other software which uses Microsoft login. I have some blacklisted domains including Microsoft's ones, that were recommended to blacklist due to privacy issues. But, again, every other software works perfectly fine. Some of the strings in the hosts file blocks it, but there is 600+ strings with Microsoft domain names and I don't really know which one it is. Clearing an entire hosts file helps, but that's not a solution, about that in the end of description.

You can see packet negotiations in the attachments. If someone will contact me in a more private environment, I may send the entire capture results etc, since I have public IP.

After talking to Mojang Support for almost 3 days, they sent me HERE with my problem:

"Unfortunately, specific technical issues are difficult to diagnose remotely due to differences with individual computers/settings, and other variables. As such, we are unable to provide individualized technical support, limiting our technical support to troubleshooting at this time."

"We encourage you to visit our help center and FAQs; there are many troubleshooting guides that may be able to solve the issue you have reported. If those guides could not fix your issue, feel free to check out the bug tracker, where you can report the issue directly to the developers. We suggest searching for your issue prior to submitting a bug report, as it may have already been reported, and to avoid duplicates. Additional guidelines can be found here."

Why it is important:

There are many people paranoid about their privacy even more than I am, especially when talking about Microsoft. A lot of their domains are in public registers that are recommended to block. OOSU10, DWS just as examples of 1-click software, not to mention literally millions of guides. Noone going to risk their privacy just to play an indie game.

Here are suggestions:

1) Use a bridge: Somehow send an entire login operation through servers, which won't be blocked. Like your MOJANG AUTH servers. Somehow encapsulate the packet so it won't be blocked by it.

2)Use the same login mechanics, that are used in every other software. Visual studio authentification works perfectly fine somehow.

3) Change domain name into hardcoded IP or just change domain name to the one, that isn't contained by popular hosts files

4) Authentification, which opens a window in a browser to login, sending back to Minecraft launcher after?
