Hi @Mehmet Arın Cengizm, 

Welcome to the Microsoft Q&A forum.  

Based on your description, your student verification is complete and eligible for the Microsoft 365 Student offer, but the subscription does not start because checkout ends with the message “A problem occurred on our side. Please try again later.” We appreciate the thorough steps you have already taken across browsers, devices, private sessions, cache cleanup, and both TR and US marketplaces. 

This behavior can occur when a previous checkout attempt leaves a stale commerce token or a pending order on the account. It can also happen when the marketplace region or billing profile does not fully match the verification region, or when the payment provider declines the initial authorization behind the scenes. These conditions stop the subscription from being created even though verification is complete. 

To resolve this quickly and accurately, we’ll need to involve Microsoft’s Billing Support team, as they have the tools to review your account, confirm the charges, and process any necessary refunds. Since your account is managed by your school, you can reach out to your school’s IT department for assistance. If the issue cannot be resolved internally, your IT administrator can submit a support request directly to Microsoft Billing team for backend assistance.   

1. Sign in to the Microsoft 365 Admin Center using your admin credentials.   

• If you don’t have admin permissions, please contact your organization’s IT administrator to submit support ticket on your behalf.  

2. Open Help & Support:   

• Click the green Help & Support button, usually located at the bottom-right corner of the Admin Center dashboard.  
• This will open the support pane.  

3. Search for assistance:   

• In the search bar, type “I need to check and reset my subscription.”  

4. Set preferences & submit 

• Choose your contact method, time zone, and language. Provide details of the issue (attach files if needed), then click Contact me. 

To help the support team assist you quickly, please have the following ready:  

• Invoice number or reference  
• Subscription ID (if applicable)  

The support team may be able to reissue the invoice depending on your account type and region.  

Or you can contact them via phone number to Microsoft Support: Customer service phone numbers - Microsoft Support - Select your country/region own phone number for support.  

Looking forward to your response and wishing you a great day ahead.
