NSPOSIXErrorDomain:100 on Safari only 14.8 and above.

• Version: 14.8 and above (14.8, 14.9, and 14.10)
• Platform: Windows

What steps will reproduce the bug?

A simple GET request using express framework is working fine on all browsers but failing on Safari for iOS and Mac with an error NSPOSIXErrorDomain:100. Degrading NodeJS to 14.7 is resolving the issue immediately. Any tips?

Can you post steps to reproduce using only built-in modules (i.e., no express)?

FWIW, NSPOSIXErrorDomain:100 is EPROTO, meaning Safari complains about protocol trouble. It's possible it doesn't like the Keep-Alive: timeout=<seconds> header Node.js started sending in v14.8.0 (commit 36fd3da) but it seems unlikely.

FWIW, it's possible that aforementioned commit contains a bug that #35138 addresses.

Closing, no follow-up.

I just installed NodeJS v14.11 on our server and I still get the same error. Degrading to v14.7 is resolving the issue immediately.

@fadijabi #35138 hasn't been released yet but you can build from source to try it out, it's on the v14.x-staging branch.

If #35138 doesn't fix it, then please post steps so I can reproduce locally.

This is to confirm that #35138 fixed the issue.

Good to hear, thanks for following up.
