Most likely, the main problem is with the connection, but this error could also be caused by something else.

The error could also be caused by a firewall or internet security app on your device that is not from Microsoft. This error can also be caused by one of Intego’s Mac apps, like Net Nanny or VirusBarrier.

What’s causing NSPOSIXErrorDomain on Mac
“NSPOSIXErrorDomain:28” may give a hint as to what the real problem is. POSIX, which stands for Portable Operating System Interface, is a broad computing standard that applies to APIs. This suggests that it may be a fairly low-level problem with Safari or macOS itself.
It’s important to remember that not everyone can reliably cause this error, and opening a lot of browser tabs or windows won’t make it happen. The part of the error message that says “No space left on device” isn’t true in terms of the affected Mac’s general disc drive capacity, since there don’t seem to be any disc space problems or swap/vm limitations. No matter what the problem is, we can be pretty sure that Safari will fix it in a future update.
