Hi,

Thank you for your input. We reproduced the issue; please stay tuned.

Note for the team - works with node version 16.13.0.

I do not believe this is M1 specific. I've had this problem on BOTH my M1 and previous generation MacBook Pro. My comparable test and problem: https://stackoverflow.com/questions/71022754/testcafe-fails-to-connect-to-localhost-on-osx

[VasilyStrelyaev]

Thank you, @scheidm! I have reproduced this error on an x86 Mac as well. I will update the issue title.

[joleek]

Hey there, do we have any updates on this issue? This is also happening to me :)

[scheidm]

I was able to get around the issue by reverting to a previous version of NodeJS. Maybe that will help people find work-arounds and solutions

[VasilyStrelyaev]

@leekkww, we have no updates at the moment. We will post in this thread once we have any news.

@scheidm, thank you for sharing the workaround.

[janwirth]

Going back to node16 also solves it for me. I recommend tj/n as version manager.

[srbagg]

not working v16 also. Any updates on possible workaround / fixes?

[github-actions[bot]]

No updates yet. Once we get any results, we will post them in this thread.

Getting same issue on linux (almalinux:8.6-20220512) as well.

[VasilyStrelyaev]

Thank you for the additional information!
