I cannot submit support request in JIRA support.

After I click the submit button, it will say: Something went wrong, please try submitting your request again.

An always like this!

If I want to directly contact them, they also re-direct to the same place to create support request.

Hi NGATDev,

On August 21 we didn't have any incidents related to support.atlassian.com.
On August 20 only jira.atlassian.com was upgraded, but it didn't affect our support site.
Have you tested creating the ticket using another browser?
Also, when you try to create the ticket, can you open the developer tools on your browser to check if it will show any other error?

Regards,
Angélica

I have changed browser, it still having this problem.

errors in developers console:

HTTP504: GATEWAY TIMEOUT - The request was timed out waiting for a gateway. GET - https://www.googletagmanager.com/gtm.js?id=GTM-MR6PJQR&l=dataLayer

0: Unable to get property 'SavePersonalAndPaymentData' of undefined or null reference

Thank you for the details.
I've checked here and it looks like the error 'SavePersonalAndPaymentData' shows on MS Edge and on Chrome it should work.
Have you tested using incognito mode?
Have you tested using another computer? It looks like something on the browser that is preventing the ticket from being created.
