What Causes Blue Protocol Error 102?

There are several possible reasons why you might encounter Blue Protocol error 102. Some of the most common ones are:

Network issues:

The Blue Protocol Error 102 might be caused by a poor or unstable internet connection, or by a mismatch between the IPv6 and IPv4 protocols.

If the game’s servers are optimized for IPv4 and you are using IPv6, this can lead to connection errors.

GPU issues:

The error might also be caused by the game’s default setting that uses the integrated GPU instead of the dedicated GPU. The integrated GPU is usually less powerful than the dedicated GPU, and it might not be able to handle the game’s graphics. This can result in the game crashing or freezing during the launch phase.

Corrupted game files:

The error might also be caused by corrupted or missing game files. This can happen due to various reasons, such as incomplete installation, faulty updates, malware infection, or accidental deletion. Corrupted game files can interfere with the game’s functionality and cause Blue Protocol Error 102.
