For two weeks I get a 504 Gateway Timeout when clicking 'pay' links in invoices from vendors. I've cleared my history, rebooted computer (MacBook Air). Help?

I appreciate the efforts you've made to resolve the 504 Gateway Timeout error message when trying to pay an invoice, @PeggiB. Let me provide additional help.

There are some reasons to consider why the error 504 Gateway Timeout occurs:

• Overloaded server or slow internet
• Network issues causing communication delays between servers
• Website downtime or expired domain

To begin, let's reboot your internet router and modem to check if this is an internet connection-related matter:

1. Unplug both the router and modem.
2. Please wait at least 30 seconds, plug in the modem, and turn it on.
3. Wait at least a minute, then plug the router back in.
4. Press the power button to turn it on if needed.
5. Wait at least 2 minutes before using the device until the internet connection returns.

Once the internet connection returns, let's access different private browsers to pay invoices. For some reason, a web page's temporary internet files stored in a cache can become corrupted, which leads to unusual behavior.

Here's how to access different private windows:

• Safari: Command + Shift + N
• Google Chrome: CTRL + Shift + N
• Mozilla Firefox or Microsoft Edge: CTRL + Shift + P

Furthermore, let's record the invoice payments to ensure accurate data in QBO.

I'd be happy to help with any questions about paying an invoice or other QuickBooks-related concerns. Have a good one.

This is frustrating. I have followed all of QuickBooks' suggestions, but nothing seems to work. I'm still receiving the same status error, 504. I've opened numerous tickets about this issue, but QuickBooks IT hasn't provided any effective solutions. Even after escalating the tickets, the problem remains unresolved. This is definitely affecting my financial reports and account status.

You need to pay your bills to vendors, correct? Try to openning your QBO account on any private/incognito browser. Did you encounter the same problem?

I'm trying to match customer payments with over 400 invoices, but I'm having trouble doing so. It's incredibly frustrating. I have followed all the steps provided by support, but nothing seems to work.
