Nintendo Switch error 2110-4004: the internet connection was lost after the console entered sleep mode
Evidence linked to this decision

Medium
Quick answer
2110-4004 means the internet connection was lost after the console entered sleep mode. Keep the full message and test one change at a time. Compare a cold connection with one sleep/wake cycle to prove whether sleep is the trigger.
Safety first
Stop and check this first
- Do not format a microSD card, initialise the console, weaken router security, disable a firewall, change DNS, IP or account country, or delete software unless the exact official branch requires it. Back up transferable captures first and never open the console.
Safe checks you can perform

What a technician must be able to justify
A technician is coming
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Escalate the exact failed branch, not the console
What they doEscalate with evidence: Nintendo Support should confirm the code branch and console state. Involve the ISP or router maker only when the same network fault is reproduced outside the Nintendo service. Provide 2110-4004, the affected title or service, storage destination, system version, connection, and the exact check that failed. Require that boundary to be reproduced before approving repair, account intervention or replacement hardware. Does the connection work after restart and fail only after one sleep/wake cycle?
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Checks and evidence, step by step
Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

Preserve the exact context

Procedure
Photograph the full code and message, then record the console model, system version, action, connection type, time and network-test result.
Do not format a microSD card, initialise the console, weaken router security, disable a firewall, change DNS, IP or account country, or delete software unless the exact official branch requires it. Back up transferable captures first and never open the console.

Compare a cold connection with one sleep/wake cycle to prove whether sleep is the trigger.
No special tools
Procedure
Restart the console, confirm adequate charge, create a fresh internet connection and install the latest official update. Then test sleep and wake once near the router. Expected result: Yes; restart works and wake fails — A working cold connection proves the SSID, password and basic path can work. The failure is specifically the post-sleep reconnection state. No; it also fails immediately after restart — Failure from a cold start invalidates the sleep-only hypothesis. Return to SSID discovery, credential and alternate-network isolation.
Do not format a microSD card, initialise the console, weaken router security, disable a firewall, change DNS, IP or account country, or delete software unless the exact official branch requires it. Back up transferable captures first and never open the console.

Stop point
No special tools
Procedure
If 2110-4004 returns after the complete pass, stop and use the persistent-result branch. After the matching documented correction, retry once. If the code returns, stop repeating resets and give Nintendo Support the exact context and results.
Do not format a microSD card, initialise the console, weaken router security, disable a firewall, change DNS, IP or account country, or delete software unless the exact official branch requires it. Back up transferable captures first and never open the console.

What it means
Nintendo's official support article for 2110-4004 says the internet connection was lost after the console entered sleep mode. The code identifies a documented branch; it does not by itself prove a failed console, router or account. A working cold connection proves the SSID, password and basic path can work. The failure is specifically the post-sleep reconnection state. Failure from a cold start invalidates the sleep-only hypothesis. Return to SSID discovery, credential and alternate-network isolation.
