Hello, @Aleem Shaik.
This is not the experience we would like you to have when contacting our support. Let's perform some troubleshooting steps to make sure that you're able to successfully contact our Customer Care Team.
First, let's access your account using a private browser or an incognito window.
- Google Chrome: Ctrl + Shift + N
- Mozilla Firefox: Ctrl + Shift + P
- Internet Explorer: Ctrl + Shift + P
- Safari: Command + Shift + N
If you're able to successfully contact us, I'd recommend clearing your browser's cache and cookies. However, if you're still getting the same results, you can use a different browser or device. You can check this article to fix unexpected browser behaviors: Troubleshooting browser problems.
If you're still setting the same error prompt, I recommend contacting our QuickBooks Online Technical Team. They have the tools to take a closer look as to why you’re still experiencing an error 502 bad gateway.
You can update this post on how it goes and if there's anything else you need. I’m always here and ready to help.
