277
Roblox 277 on PC: connection to the game server is lost
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
Roblox lost the connection to the experience server (277). Rejoin from another network, such as a phone hotspot, to find out whether the drop comes from your connection before you reinstall anything.
Safety first
Stop and check this first
- If the drop happens mid game, do not change router settings or open ports because a video or forum says so: Roblox sends that review to your internet provider.
Safe checks you can perform
- Another internet connection
- Clean Roblox reinstall on Windows
- Date and time on phone, tablet or Chromebook
- Minimum requirements and interfering software
Leave these tasks to a qualified professional
- Do not attempt this professional task: Roblox Support with the case documented

What a technician must be able to justify
Technician visit
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.
Roblox Support with the case documented
What they doIf code 277 persists on another network and after a reinstall, Roblox Support reviews the case from the code, the device and the steps you already took.
They must show youthe reply to your request with its number.
In writingthe case number, the device and operating system and the checks already ruled out.
Line check by your internet provider
What they doIf code 277 only appears on your usual connection, the provider checks the line, the router it supplied and any outages or blocks on its network.
They must show youtheir line test result and any open incidents in your area.
In writingthe incident number and what was changed (router, settings or network fault).
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Another internet connection
- Who:
- you.
- How:
- close Roblox, connect the device to a different network (another Wi-Fi or a phone hotspot) and join the same experience again.
- Result that matters:
- whether you get in on the other network without code 277.
- If you get in:
- the cause is your usual network; the next step is your internet provider.
- If the code returns:
- your network is ruled out as the main cause; move on to reinstalling Roblox.
- Evidence to keep:
- which networks you tried, the time of each attempt and whether the code appeared.
Evidence: Error Code 277: Lost connection to the game server, please reconnect | Please check your internet connection and try again
Clean Roblox reinstall on Windows
- Who:
- you.
- How:
- uninstall Roblox (Windows 10: Start > Settings > Apps > Apps & features; Windows 11: Control Panel > Programs > Programs and Features). Press Win+R, type CMD, run cd AppData\Local and then rmdir /s Roblox, answering y. Restart the PC and install Roblox again.
- Result that matters:
- whether the error is gone with a fresh, up to date copy of the app.
- If it is gone:
- corrupted or outdated app files or data were the cause.
- If it stays:
- the install is ruled out; code 277 points to the connection.
- Evidence to keep:
- the reinstall date and whether the error came back on the first try.
Evidence: Error Code 277: Lost connection to the game server, please reconnect | Please check your internet connection and try again
Date and time on phone, tablet or Chromebook
- Who:
- you.
- How:
- if you play on iOS, Android, Fire OS or ChromeOS, restart the device (off for about 30 seconds), open Settings and check that the date and time are correct.
- Result that matters:
- whether Roblox connects after the restart and time fix.
- If it connects:
- used memory or a wrong clock was blocking sync with the servers.
- If the time was already right and the error stays:
- rule this out and try another network.
- Evidence to keep:
- a screenshot of the device date and time before the change.
Evidence: Error Code 277: Lost connection to the game server, please reconnect | Please check your internet connection and try again
Minimum requirements and interfering software
- Who:
- you.
- How:
- confirm you are not playing on a virtual machine or cloud computer, run a speed test and check whether your antivirus or another third party app has blocked Roblox.
- Result that matters:
- whether speed reaches 4 to 8 Mb/s or more and whether any program blocks Roblox.
- If speed falls short or something blocks it:
- fix that first; Roblox does not support those setups.
- If everything checks out:
- the problem is outside your PC; talk to your internet provider.
- Evidence to keep:
- the speed test result and the name of the installed antivirus.

What it means
Roblox describes 277 as the client app failing to establish or keep the network connection with its servers on PCs, Macs or mobile devices; the message asks you to reconnect and check your internet. The code does not separate a Wi-Fi drop, a provider problem or corrupted app data, and it does not mean your account has any restriction. The useful order is another network, a clean reinstall and, if it persists, your provider.
