1. Refresh ChatWork after 60 seconds
A 500 error can be temporary. Press Ctrl + R or Cmd + R. Avoid repeatedly clicking send or upload because duplicate actions may happen after the server recovers.
What is ChatWork 500 internal server error?
The ChatWork 500 internal server error means the ChatWork server could not complete your request. In simple words, ChatWork received your action, such as opening a room, sending a message, uploading a file, or logging in, but something failed on the server or during the connection process.
Quick answer: First refresh ChatWork and check whether other users are affected. If it happens only on your device, clear browser cache, disable extensions, turn off VPN/proxy, and try another browser or network.
Quick Diagnostic Table
| Symptom | Likely Cause | Best First Fix |
|---|---|---|
| ChatWork fails for everyone | Server outage or maintenance | Check status and wait |
| Error only in Chrome | Cache, cookies, or extension issue | Clear site data and disable extensions |
| Error on office Wi-Fi only | Firewall, DNS, proxy, or blocked script | Try mobile hotspot or another DNS |
| Error while uploading files | Large file, timeout, or unstable network | Compress file and retry |
| API returns HTTP 500 | Backend/API-side failure | Retry later and log request details |
How to Fix ChatWork 500 Internal Server Error
2. Check if ChatWork is down
Ask a teammate to open ChatWork, test on mobile data, or check outage reports. If many users are affected, the issue is probably not your browser or device.
3. Open ChatWork in incognito mode
Incognito mode disables many cached sessions and extensions. If ChatWork works there, your normal browser profile likely has a cookie, cache, or extension conflict.
4. Clear ChatWork cache and cookies
Go to browser settings, search for site data, find ChatWork, and remove stored data. Then sign in again. This often fixes broken sessions and old authentication tokens.
5. Disable extensions temporarily
Ad blockers, privacy tools, script blockers, translation plugins, and security extensions may interfere with ChatWork scripts. Disable them one by one and reload ChatWork.
6. Turn off VPN, proxy, or custom DNS
Some VPNs and proxies route requests through unstable or blocked servers. Turn them off, reconnect, and test ChatWork again using your regular network.
7. Try another browser or device
Test ChatWork in Edge, Chrome, Firefox, Safari, desktop app, or mobile app. If only one device fails, update that browser or reinstall the ChatWork app.
8. Contact ChatWork support with details
If the error continues, collect the time, browser, device, workspace, room URL, action performed, screenshot, and console/network error. This helps support identify the failure faster.
For Admins and IT Teams
If several employees report ChatWork 500 errors at the same time, do not waste time reinstalling browsers on every machine. First check firewall rules, proxy logs, DNS resolution, SSO login flow, corporate VPN routing, and any security gateway that may be modifying requests.
Network
Test from office Wi-Fi, mobile hotspot, and home network.
Browser
Check extensions, outdated versions, and corrupted profiles.
Account
Confirm login permissions, SSO, and workspace restrictions.
