Common Causes and Solutions for This Error

While the message is unspecific, there are some common triggers for this error that users can check for. Here are some of the common causes and potential fixes:

Outdated Browser or Cache

Using an outdated or unsupported browser is a common reason for errors in Misskey. The app regularly rolls out updates with new features that may not work well on older browsers.


  • Update your browser to the latest version
  • Try clearing your browser cache and reloading the page
  • Use supported browsers like Chrome, Firefox, Edge etc

Server Outage or Overload

If the Misskey server you are connected to is down for maintenance or overloaded with traffic, it can throw generic errors for users.


  • Check the server status page or social media for outage alerts
  • Try connecting to the instance later when it is back up
  • Inform admins if outage seems prolonged

User Account Issues

Problems with your user account like being blocked, suspended or reaching upload limits can also lead to errors.


  • Check if your account has been blocked by admins
  • Confirm you haven’t reached file storage or post limits
  • Try logging out and logging back in

Plugin Errors

Misskey allows users to install custom plugins and themes. A problematic plugin can cause errors for your instance.


  • Try disabling newly installed plugins
  • Check plugin compatibility for your Misskey version
  • Ask admins to check server logs for plugin issues

Network Connectivity Issues

Any kind of disrupted internet connectivity like weak signals, switching networks, restricted networks etc can interfere with Misskey loading properly.


  • Check your internet connection stability
  • Switch to a better network if possible
  • Use a VPN or proxy if your network has restrictions

Misskey Version Mismatch

Using a very outdated Misskey app while your instance runs a newer version can also trigger errors sometimes.


  • Go to App Settings and update to the latest Misskey app
  • Check the Misskey version on your instance and update accordingly

Incorrect Misskey Config

Admins need to modify Misskey config files with custom settings for attributes like storage, caching, security etc. Incorrect configs can break things.


  • Inform your Misskey instance admins about the issue
  • Check the admin changelog for recent config changes
  • Help admins troubleshoot configuration errors

So in summary, this generic error has a wide range of potential causes. By methodically checking different solutions, users should be able to resolve the problem and continue using Misskey smoothly.

How to Better Troubleshoot the “An Error Has Occurred” Message

Since this error message is vague, troubleshooting the exact cause can be tricky for regular users. Here are some tips to better troubleshoot and communicate the problem:

Check the Timeline

Check your Misskey timeline and notifications for any server outage alerts or error updates from admins. They may have posted about known issues.

Look For Error Logs

See if your instance provides public error logs. If yes, look for logs around the timeframe the error occurred to identify possible causes.

Try Basic Troubleshooting

Search Misskey Issues

Search the Misskey source code repositories for open and closed issues related to the error message to see if a cause is identified.

Check Third-Party Services Status

Prompt your Misskey instance admins to update the Misskey version if it is very outdated and susceptible to bugs.

So in summary, providing additional troubleshooting context to server admins is key to resolving “An error has occurred” faster. Following general debugging best practices helps identify the root cause.

Improve Server Infrastructure

Adding server capacity, bandwidth, caching etc helps handle traffic spikes and prevents downtime and errors.

Maintain Regular Backups

Regular backups ensure Misskey instances can be restored quickly in case of crashes or data loss.

Update Frequently

Servers admins should regularly check and apply Misskey updates to get bug fixes and security patches.
