Getting the following error on subscription page Subscribe Something's not working. Give us a few minutes and try again. If it still doesn't work, please contact us.

Hello, 1935 1470 6451 274. 

Thank you for bringing this matter to the Community. I have a few troubleshooting steps you can try to fix this error when subscribing to QuickBooks Online. 

There are times that the browser is full of frequently-accessed page resources, thus accumulating and corrupts the browser cache causing the run time user interface to malfunction.

To start, access QuickBooks account using a private/incognito browser. You can use the shortcut keys below: 

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Safari: Command + Option + P   

If it works, we'll go back to your regular browser and clear the cache to get rid of the stored junk files. You can also use other supported browsers as an alternative and to roll out the possibility of a browser-related issue.      

However, if the same thing happens, I suggest reaching out to our customer support team. They'll be able to initiate a screen-sharing session to take a closer look to isolate this issue and help you with your subscription. 

To contact our support, here's how: 

1. Go to the Help icon.
2. Choose to Talk to a human.
3. Enter "Talk to a human" again in the search bar.
4. Select I still need a human, then click Contact Us. 

Just a heads up, due to the pandemic we have limited staffing. To make sure you get prioritized on your concern. Please check out our support hours and contact us at a time convenient: ​​Support hours and types.
