Credentials Cannot Be Null Minecraft What to do. Causes of servers failure

Minecraft is largely popular due to the network mode. However, when connecting to the server or when it creates it often occurs in the entry error Credentials Cannot Be Null. It completely blocks the possibility of entering the network, which is especially problematic for those who are used to creating network games.

Causes of servers failure

The main reasons are the differences of versions with the server - many players downloaded the "pirate" client, and try to go to the official server. For obvious reasons, access is blocked, because the client must also be licensed. According to other sources, anything blocks the network on your computer (for example, VPN applications, hamachi).

How to fix the entry error

We have collected several basic moments that should be viewed first. Alternately check each of them, starting with the easiest.

Data reset

A simple variant of the correction of the situation becomes a reboot. Make a restart for the client, PC and disconnect reboot the modem. Exit your account and go to it again. Disconnect the antivirus at the time of connecting to the server and other similar blocks. Release the system from unnecessary software as much as possible (look in the background and tray), which does not take part in Minecraft.

Files

We try to make changes to the file "Server" (or "Server.Properties"). It can be found in the folder where the data of the Mine Server is stored. Since the file cannot be opened just like this, we do it through a notebook. Opening the text, you should find in it the following line: online-Mode \u003d True. It changes only in it. Instead of the word true. Insert value false. Basically, such actions help players with non-license customers who still seek to get to official servers.

Third-party service ely.by.

If you are not familiar with Ely.BY., Be sure to "google" information. This is the system of skins and additional authorization in the world of minecraft. With this resource you can create your own networks. Register with your company where the mode is available. "ELY for network game". After that, you can create network locations again. Simply put, Ely.BY is just an alternative to the usual Mojang.

Game itself

Many users to solve the entry error "Credentials Cannot Be Null" changed the game version. Be sure to test a few previously released Minecraft modifications. Pre-delete the game that is now installed. The most reliable operation is shown versions 1.7.10 and 1.11.2. This does not mean the transition to them, but it is still worth trying.

Your Os.

The operating system is always full of bugs. Be sure to test it on errors and correct them using optimizers ( Advanced Systemcare, CCleaner other). Also additionally remove the software installed in the past few days. Sometimes programs block output to the server, and only their uninstallation will solve the situation.

Finally, just wait for a while. There is always the likelihood of problems in access to Minecraft sites. After a few hours, repeat your attempts. At the end, I would like to insert a video instruction for properly configuring the Hamachi network, since this failure often occurs when you try to connect through this program.
