}What happened?
Sporadically, the following error occurs:
TypeError: fetch failed
error properties: Object({ cause: Error: connect ECONNREFUSED 127.0.0.1:62837 })
at node:internal/deps/undici/undici:12618:11
Caused by: Error: connect ECONNREFUSED 127.0.0.1:62837
error properties: Object({ errno: -4078, code: 'ECONNREFUSED', syscall: 'connect', address: '127.0.0.1', port: 62837 })

at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1555:16)
We have a large number of tests and I couldn't find a pattern which tests fail and which not. It seems to be completely random. I even ran the tests on different machines, the error occurs seemingly on any machine (at least Windows 10 and 11).
The error did not occur with webdriverio 8.
What is your expected behavior?
The error should not occur.
How to reproduce the bug.
I am not able to create a reproducible example since the error seems to occur completely randomly.
