Getting a 504 Gateway Time-Out Proxy Error – How Do I Fix This? or Why Am I Seeing a 504 Gateway Time

504 errors are usually server-side, but yeah, sometimes your connection acts up too.

If refreshing doesn’t work, try changing your DNS to Google’s (8.8.8.8) or Cloudflare’s (1.1.1.1).

Works like a charm for me when my ISP’s DNS is being slow.
