I need help.

[SackyyPL]

Let's start with the fact that I used MCC a long time ago, and now everything has changed.
I fired up the file "MinecraftClient.exe" and a file named "MinecraftClient.ini" was created for me.
Everything I set up looks like this:
login=xSacky
password=mypassword
serverip=craftplay.pl
type=mojang
method=mcc
I didn't change anything else.
When I then click on the exe file it won't connect me, what am I doing wrong or what else should I do?
Please help =)

Try filling in the login field with the email address of the account.

If the account type configured in the settings is "mojang", there should be a log like this: "Connecting to Minecraft.net..." (not Microsoft)

I don't have an unmigrated mojang account so I can't verify this, but in version 1.19 and above, mojang accounts are not able to get the keys needed for message signing.

I changed the "type=" option to "microsoft" and suddenly it worked, thank you for your help 👍

because I had my account migrated to microsoft.

I currently have another problem, after joining the server after a few moments I get disconnected. It is like this all the time.
