Problem solving on site

For an exam with FLOWlock, it is recommended that every participant comes in a little early and start the FLOWlock demo. Any issues with FLOWlock should be shown at that point, and you will have some time to fix it before the exam starts.

If there is a problem in the browser, i.e. content not loading correctly, or similar issues, you can try to perform a “refresh” in the browser functions in the upper left corner. This functions like a normal refresh in a regular browser. More often than not, this solves any issues with the FLOWlock browser.

Classic methods of problem solving can often be of use here as well: Shutting down the browser and starting it again. Rebooting the computer and try again. These are the easiest to try out and can often fix small issues with the FLOWlock browser.

White screen is showing / Internet security programs are interfering with FLOWlock

Sometimes, when you try to enter the exam, the FLOWlock browser will show a white screen instead of opening the exam. Or you might experience FLOWlock slowing down during the exam. This is usually due to internet security programs, like McAfee and Symantec, trying to prevent the FLOWlock browser from locking down the computer.

We recommend temporarily turning off the internet security program while the exam is running. Normally these internet security programs have the option to disable themselves for a period of time or until next reboot; when it has been disabled, the FLOWlock browser will function normally again.

FLOWlock browser is not starting properly

Try uninstalling the FLOWlock browser, download it again and install it. Sometimes, a program appears to be installed correctly when it is not. And you may want to reboot your computer between uninstalling the FLOWlock browser and downloading it again, to make sure it is a clean install.

Missing internet connection

If the internet connection is lost during the exam, the participants have to contact the invigilators immediately. In order to re-establish an internet connection, the invigilator can perform the following steps in order. If the internet connection is re-established, you can stop going through these steps and let the participant continue the assignment.

1. First of all, ask the participant to perform one more task or edit something in their assignment. The system performs a check of the internet connection whenever there is new data to be saved.
2. By pressing the cogwheel in the left side of the screen, next to the red “Exit”-button, you can open the “Invigilator menu.” As the invigilator, you have the option to perform a range of administrative actions including “Manual reconnect,” which can solve this issue.
3. Connect an Ethernet cable to establish a direct cabled connection to the internet.
4. Restart the browser using the question mark "About" in the browser functions in the upper left corner of the screen. Choose “Invigilator options,” close the browser and restart FLOWlock browser.
5. As a last resort, the participant can continue the assignment offline and remember to save locally to the hard-drive regularly. This local copy can be handed in, when the FLOWlock browser has been closed down without handing in.

Frozen browser

1. If this happens in relation to a missing internet connection, first try to re-establish the internet connection with an Ethernet cable.
2. If an internet connection is established, try to close down the browser through the red “Exit”-button and restart the browser.
3. If the browser cannot be closed down using the “Exit”-button, close it down by using the Question mark “About” and choosing “Invigilator options”. Close down the browser and restart the FLOWlock browser.
4. If it is not possible to close down the browser, you have to force reboot the device. At this point, data can be lost, if this is happening in connection with a missing internet connection.

The computer has been force rebooted and is in a locked state

When the computer is force rebooted during a FLOWlock/FLOWmulti, it will automatically run a process to exit the browser. If this does not happen automatically, and the computer is in a locked state, you can follow these two steps to resolve it manually:

1. Re-open the FLOWlock/FLOWmulti exam through the flow and exit or hand-in to quit the browser correctly.
2. Open the FLOWlock-browser directly on your computer (Application name: LockDown Browser OEM). This will open a small window, where you can choose to exit the browser manually and then the computer will return to its normal state.

[MacOS] ARDAgent is blocking the FLOWlock-browser

On a Mac you may get the following warning and be forced out of the FLOWlock-browser. 

This happens if Sharing is enabled on the Mac and you need to quit the FLOWlock-browser. Once that is done, you go to System Preferences -> Sharing and turn off the following:

• Screen Sharing
• Remote Login
• Remote Management
• Remote Apple Events

After these options have been turned off, you can start the FLOWlock-browser again.

[MacOS] Siri is blocking the FLOWlock-browser and can't be closed

On a Mac you may get a warning about Siri being open and you need to close it manually. In our experience this only happens if the Siri app window is open while starting FLOWlock, like this:

If this happens, you will need to close the FLOWlock browser and you should be able to start it up immediately after. But you may also want to disable Siri, so it does not affect the FLOWlock browser.

Note: We recommend disabling Siri to avoid any issue during the FLOWlock exam.

You can disable Siri by opening the settings and choose Siri:

And in the Siri options, you make sure to deactivate the "Enable Siri" option. This will disable Siri and after taking the FLOWlock exam, Siri can be enabled again.
