Error message: “Oops! Check your configurations”
This message may appear when Nexam detects an issue with your device, browser, or Internet connection.
Before an assessment, Nexam checks, among other things:
whether your browser can communicate with the platform;
whether data can be sent to Nexam;
your upload speed;
the stability of your connection.
If a blocking check fails, you must resolve the issue and run the validation again before you can proceed to the assessment.
1. Check your Internet connection
To help ensure that your assessment runs properly, Nexam’s general technical requirements are at least:
10 Mbps download speed;
10 Mbps upload speed.
Use a wired Ethernet connection whenever possible and avoid having other devices or applications heavily use your connection during the assessment.
You can check your connection before the assessment:
Open Validate your device in Nexam.
Open Connection speed test.
Click Start.
This preliminary test measures latency, download speed, and upload speed.
See Check Your Internet Connection Speed and Stability in Nexam for more information.
2. Understand the pre-assessment validation
When you access an assessment, Nexam performs a Technical requirements validation before allowing you to proceed.
This validation is separate from the test available under Validate your device.
Upload speed
Nexam checks your connection’s ability to send data to the platform.
Below 2 Mbps: the validation fails and access to the assessment is blocked.
Between 2 and 5 Mbps: a warning is displayed. You may continue, but your connection is slower than recommended.
Above 5 Mbps: the validation is successful.
These thresholds determine whether this check allows you to proceed to the assessment. They do not replace Nexam’s general technical requirements.
Connection stability
Nexam also checks that exchanges with the platform remain functional during several consecutive checks.
A connection can have good speed while still experiencing interruptions.
If your connection is considered unstable, the validation fails and access to the assessment is blocked.
After resolving the issue, click Run validation again.
3. Improve a slow or unstable connection
If your upload speed is insufficient or your connection is unstable:
use a wired Ethernet connection whenever possible;
if you are using Wi-Fi, move closer to your router;
close applications that are using significant bandwidth;
temporarily pause file synchronization services;
limit network use by other devices;
restart your modem or router if needed;
try another network when possible.
Then run the validation again in Nexam.
4. Check your network settings
If you are using a school, institutional, or corporate network, security rules may prevent your browser from communicating correctly with Nexam.
Check whether:
a firewall is blocking access to Nexam;
a VPN is restricting exchanges with the platform;
a security or privacy browser extension is blocking certain requests.
If the issue disappears when you use another network, the original network may be causing the problem.
Contact your IT team if you are using a managed network or device.
5. Check your security software
Some antivirus, firewall, or security software may block exchanges required by Nexam.
If you are using a personal device, check your security software settings to make sure it is not preventing Nexam from communicating over the Internet.
If the device is provided or managed by your organization, contact your IT team before changing any security settings.
What should I do if the issue persists?
If you are blocked at the Technical requirements step:
Note the name of the check that is failing.
Follow the corresponding recommendations.
Click Run validation again.
If the issue persists, contact technical support and provide:
your name;
the email address you use in Nexam;
the name of the assessment;
the name of the requirement that is failing;
the browser and type of device you are using;
a screenshot of the message displayed.
This information will help the support team identify the source of the issue more quickly.
