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.
