How to Fix Rainbow Six Mobile Error Code (1115, 135, 1252, 11)

Many players are excited to jump into fast matches in Rainbow Six Mobile. The gunplay feels sharp. The rounds are short. The tension is real. But then an error code suddenly appears on the screen. The game kicks you out. Or matchmaking fails. Or the login does not work.

In this guide, we will break down four common error code messages in Rainbow Six Mobile and explain how to fix error code problems step by step.

Why Does Rainbow Six Mobile Show an Error Code?

Before looking at each error code, it helps to understand the bigger picture.

Most Rainbow Six Mobile error code issues are related to:

• High latency (ping is too high)
• Network instability
• Packet loss
• Server communication timeout
• Weak WiFi signal
• Cross-region connection

Even if the message looks different, the root cause is often the same. Your device cannot maintain a stable connection with the game server. When that happens, the system triggers an error code.

Now let's look at the four most common ones.

1. INFO Error Code 1115

Booted from game due to high latency

This error code appears during a match. The message says you were booted from the game due to high latency. Then you are sent back to the main menu.

What does it mean?

Your connection became too slow. The server detected high latency. It removed you to protect match stability.

Common causes

• Playing on unstable WiFi
• Network congestion at home
• Background downloads
• Connecting to a distant server region

2. MATCHMAKING ERROR -- Error Code 135

Failed to enter matchmaking due to high latency

This error code appears before the match even begins. You try to queue. The game refuses.

What does it mean?

The system detects high latency before placing you in a match. It blocks entry to prevent unfair gameplay.

Why it happens

• Sudden ping spikes
• Network fluctuation
• Packet loss during server handshake
• Weak internet signal

Error code 135 is similar to error code 1115. The difference is timing. One kicks you out. The other blocks you from entering.

3. GUEST SESSION ERROR -- Error Code 1252

An error occurred while opening a guest session

This error code happens during login. Especially if you are using a guest account.

What does it mean?

The game cannot properly open a guest session. The server request failed.

Possible reasons

• Temporary server response issue
• Interrupted internet connection
• Network restrictions
• DNS routing problems

Even though this looks like an account problem, it is usually still a network-related error code.

4. TIMEOUT ERROR -- Error Code 11

A timeout has occurred

This is one of the most common error code messages.

What does timeout mean?

Your device sent a request. The server did not respond in time. The connection expired.

Why it happens

• Severe packet loss
• Unstable mobile data
• Weak signal
• Server route congestion

Timeout problems are classic network issues. If your connection is unstable, this error code may keep returning.

The Real Pattern Behind These Error Code Problems

Let's look at the four cases together:

• Error Code 1115 → High latency
• Error Code 135 → High latency during matchmaking
• Error Code 1252 → Server session communication failure
• Error Code 11 → Timeout

Different names. Same root problem. All these error code messages are connected to unstable network conditions.

You can restart your router. You can switch networks. Sometimes that works. Sometimes it doesn't. Especially if the problem is not inside your home network but in the routing path between you and the game server.

That is where a professional game network optimizer becomes useful.

1. Search for Rainbow Six Mobile, click "Boost", and select the target server.
   
2. After loading reaches 100%, you can start the game. Please keep GearUP Mobile running in the background and do not close it, so as not to affect the optimization.
   

FAQ about Rainbow Six Mobile error codes

Q1. Are all Rainbow Six Mobile error codes caused by the network?
Not necessarily. Error codes come in different types. The error codes above are all network‑related, but there may still be some that are unrelated to the network; you need to analyze them based on the error code message.

Q2. Will reducing latency decrease error codes?
Reducing latency and improving network stability means there is less obstruction between you and the server, which can indeed reduce the occurrence of error codes—so GearUP Mobile is very useful.

Q3. Is GearUP Mobile a safe application?
Yes. GearUP Mobile helps you adjust connection nodes, that is, network routes. It’s like finding the fastest and most stable road among several options, and it is completely safe.

Q4. Why don’t error codes appear all the time?
Because these error codes are related to network connection stability, and network jitter is irregular. Sudden faults can cause error codes, while under normal conditions you typically won’t encounter them.
