Clover 500 Internal Server Error | How to Fix

A 500 Internal Server Error on a Clover point-of-sale (POS) device is a generic error that means the server encountered an unexpected condition that prevented it from fulfilling a request.

This is a server-side issue, not a problem with your device itself. While it can be frustrating, there are several troubleshooting steps you can take.

Common Scenarios & Developer Insights

◼ E-commerce API (e.g., /v1/orders/{order_id}/pay)

• Users experienced intermittent errors during payment processing.

• In some instances, problems were resolved after Clover deployed backend fixes.

◼ Deleting Orders via API

• Attempting to delete open orders sometimes triggered a 500 error.

• Clover responded that a fix was deployed shortly after identification.

◼ OAuth Flow in Sandbox

• Developers reported encountering 500 errors following login during OAuth authorization in sandbox environments.

• Temporary fixes included creating a new sandbox developer account, which resolved the issue for some.

◼ Filtering Orders or Retrieving Events

• Complex or unfiltered queries (like order retrieval with filters) occasionally triggered server-side failures.

• Switching to more appropriate endpoints (e.g., using /v3/orders with proper filters) proved successful.

◼ Intermittent Data Retrieval Errors

• Some users saw periodic 500s when fetching “cash events” or other data.

• Clover engineers acknowledged inefficiencies and planned fixes in backend deployments.

How to Fix a Clover 500 Internal Server Error

• Wait and Retry:

  • The error may be temporary, caused by a brief server overload or a momentary glitch. Wait a few minutes and try the transaction again.

• Check Clover’s Status Page:

  • The error might be part of a broader outage. Check the official Clover status page to see if there are any reported system-wide issues. This will confirm if the problem is on their end and not yours.

• Restart the Clover Device:

  • A simple reboot can often resolve software conflicts. Power down your Clover device completely, wait about 30 seconds, and then turn it back on.

• Check Your Network Connection:

  • While the error is server-side, a poor or unstable internet connection on your end can sometimes interfere with communication and lead to this error.
    • Verify your Wi-Fi or Ethernet connection.
    • Try restarting your router and modem.
    • If possible, switch to a different network to see if the issue persists.

• Check for App Updates:

  • Ensure all of your Clover apps are up to date. Sometimes, an older version of an app can have a bug that causes a server error.

• Contact Clover Support:

  • If the error persists after trying the steps above, it’s time to contact Clover’s technical support team. Provide them with as much detail as possible, including the exact time the error occurred and what you were doing on the device.

Final Tip

For users encountering OAuth or API flows that lead to 500 errors, one developer shared:

“Creating a new merchant in the Sandbox and testing helped fix the problem.”

This underscores that sandbox environments can be finicky and occasionally need a fresh start.
