URL_UNREACHABLE-UNREACHABLE_5xx

[changjo]

Hi everyone I got the URL_UNREACHABLE-UNREACHABLE_5xx. Original HTTP response code number = 500 error . What was strange is that it didn't happen every time. I run my cloud function 3 times per hour, and I got this error for like 3-4 times a day. I've redeployed it several times but still got error

Hi @changjo,

Welcome to the Google Cloud Community!

The error URL_UNREACHABLE-UNREACHABLE_5xx (Response code: 500) typically indicates an issue with accessing the Cloud Function URL or a problem with its dependencies. Here are some steps you can try:

• Verify external dependencies: Confirm if the destination URL your function depends on is reachable and stable
• Run your Cloud Function locally: Test if you’re able to reach the destination URL locally
• Review your code: A user posted a similar thread here that was resolved by updating their source code
• Allocate more Cloud resources: Your Cloud Function may have too many pending requests that are aborted due to a spike in traffic, scalability configuration issues, or reaching the Cloud Run functions quota limit

As a workaround, try running a Connectivity Test to further diagnose and analyze the issue.
