I completely recognize how important it is for you to schedule your AZ-400 exam without any complications. Rest assured, I’m here to support you every step of the way to make the process as smooth as possible.
In order for us to replicate the issue and better assist you, we kindly request you to share with us a step-by-step screenshot by following the guidelines below:
Open Problem Steps Recorder (PSR) for Windows Click this link for a Mac device and start recording.
Use the new MS Edge browser (in private).
Clear the cache and cookies, then restart the browser.
Kindly login and navigate to the page where the error page shown in your screenshot is visible.
Once done, please attach the PSR file along with the other requested information via the private message I have initiated. This will enable us to investigate further and escalate the case if necessary.
Meanwhile, you may also contact the Pearson VUE support team for real-time assistance. They may be able to help you secure an earlier slot or make special arrangements, especially if you mention that your voucher is expiring soon.
The testing center also has real-time access to exam schedules and availability, so they’re in the best position to assist you. You can find their contact information at the following link (just be sure to select your region):

Furthermore, if you have used an ESI discount when scheduling your exam or are an active ESI learner affiliated with a company or organization currently partnered with ESI, it is recommended to contact the ESI Support Team. They specialize in assisting ESI learners and will work with your exam provider to address your concerns. Additionally, they can also assist with scheduling your exam. You can find their contact details in the private message.
If you require further assistance following your interaction with the ESI team, kindly provide me with your case ID. This will allow me to keep track of your case and furnish you with any updates they provide.
Let me know if further assistance is needed.
I look forward to your response. Please note that if no response is received after two business days, the case will be closed and locked. After the case is locked, we will no longer be able to respond. Thank you.
