When I try to open Minecrfat Launcher it keeps load for 10 mins and after that crash with 0x1 error.
Additionally I cannot login to minecraft.net, it stuck on verification. My assumption is it might be network region issue because even such address like https://status.cloud.microsoft/ is not working properly (most of the time I cannot open this link). Other non microsoft connections like google, facebook, steam works fine.
Environment
Microsoft Windows 11 Pro (10.0.26100 N/A Build 26100)

I mean I was searching for similar tickets and I’ve found one similar MCL-25624 but discord link doesn’t work for me and I don’t know what is the status of this ticket. So no other quick links help in this matter.
It didn´t help me either (I am the person from the post you mentioned, I was trying to get help at other posts and found this lol)

Hi, I have wonderful information, I’ve solved my issue. It may help others so I will describe what I’ve done. So, Microsoft and minecraft.net or Minecraft launcher may use different value of MTU or MSS (maximum packet size). I’ve found that any connection from my router to azure cdn is broken on TCP handshake. To solve this, you need to find out option in your router or your ISP provider need to add something called “MSS clamping” or change values of MTU/MSS to be bale communicate correctly with microsoft services. I don’t know if it will help all of you, but it may will be a good option to check or add. Ticket can be closed.
