What does "The specified network name is no longer available" mean in psping?

Question

"The specified network name is no longer available" is displayed if I include a -l in the command:

C:\IT\PSTools>psping -l 32 52.96.110.34:443

PsPing v2.12 - PsPing - ping, latency, bandwidth measurement utility

TCP latency test connecting to 52.96.110.34:443: Connected

9 iterations (warmup 5) sending 32 bytes TCP latency test: 0%

The specified network name is no longer available.

TCP roundtrip latency statistics (post warmup):

Sent = 0, Size = 32, Total Bytes: 0,

Minimum = 0.00ms, Maximum = 0.00ms, Average = 0.00ms

But it runs fine if I omit the -l:
