1, network speed problem
2. The webpage is overloaded, and there are too many people logging in at the same time, so the server can't run.
3. Is it an external network? Are there any restrictions on domestic and foreign web pages?
4. The password is incorrect
5. It took too long to open the original webpage, and the webpage has expired.
6. Website update.
What should I do if I can't get to official website after gre registration?
First of all, I suggest you wait, because it is likely that the network speed is not strong or the load is too large. A moment, please.
If possible, try different network environments.
Try refreshing yourself. Every time you enter the registration page, a waiting blue box will be displayed, and then you can't enter again after completing 100%. Hello, you can change your browser and close all banned plug-ins. Some plug-ins prohibit jumping.
The last one can only wait for the website to be updated honestly.
