Hello @Tran, Duc,
Welcome to Microsoft Q&A forum.
If you have a valid subscription(paid level), then VS 2017 Professional is available here: Downloads.
Please note, "Visual Studio Dev Essentials" subscription is not a valid subscription in this situation.
If the license/subscription is managed by your administrator, try to communicate with your administrator. If you have a valid license key but doesn’t have a valid subscription, please kindly try to contact Visual Studio Subscription team(scroll down > choose a correct option for example "Account, Subscription and Billing Support" > select country/region) for better help.
Feel free to let us know if you have any further concerns:)
Best Regards,
Tianyu
