In simpler terms, it suggests a communication breakdown between servers in the path of delivering your requested content.

Common Reasons for the 502 Error

  • Server Unavailability:The primary cause of a 502 error is when one of the servers in the communication chain (gateway, proxy, or origin server) is not responding or is unavailable.
  • Network Issues:Problems in the network infrastructure, such as timeouts, packet loss, or DNS issues, can lead to the 502 error.
  • Overloaded Servers:If a server in the chain is overwhelmed with requests and unable to process them efficiently, it can result in the 502 error.
