GitHub runner cannot send fetch with node, failing with IPv6 DNS error UND_ERR_CONNECT_TIMEOUT #3213
Description
Describe the bug
Sending more than one (sometimes two or three) requests using fetch results in DNS errors.
To Reproduce
I created a repository to reproduce this in as minimal way as possible:
https://github.com/undergroundwires/node-fetch-ipv6
I run fetch on using vite test runner on node and without any test runner. I get same results.
I realize that the first two requests are successful, I start getting the error after the second or third one.
See the test: test file
Second test (multiple fetch in order) fails, and all run fine locally. I run tests on default GitHub runners using both latest node 20 and 18. I get same errors:
Expected behavior
The requests are being sent fine, this was the case before.
Runner Version and Platform
The job runs on ubuntu-latest, see the repository linked in To Reproduce section above.
What's not working?
I get UND_ERR_CONNECT_TIMEOUT errors which is related to IPv6 issues in node.
Related issue for node: nodejs/node#41625,
Related issue for node fetch: nodejs/undic#1531
Related issue for GitHub runners not being able to do IPv6: actions/runner-images#668, #3138
