"Reached end of stream but expected 4 more bytes."

[jhertel]

I very often get the message "Reached end of stream but expected 4 more bytes." in red characters. When I get it, the function I want to call isn't executed.

I can find no pattern as to when I get it. If I give the command "expresso status" several times in a row, I sometimes get the wanted result:

VPN connected to 'Denmark' (78)

but other times:

Reached end of stream but expected 4 more bytes.

Here is an actual session in CMD; each command was executed within 1-2 seconds from the previous:

C:\ProgramsManual\Expresso>expresso status
Reached end of stream but expected 4 more bytes.

C:\ProgramsManual\Expresso>expresso status
VPN connected to 'Denmark' (78)

C:\ProgramsManual\Expresso>expresso status
Reached end of stream but expected 4 more bytes.

C:\ProgramsManual\Expresso>expresso status
VPN connected to 'Denmark' (78)

C:\ProgramsManual\Expresso>expresso status
Reached end of stream but expected 4 more bytes.

C:\ProgramsManual\Expresso>expresso status
VPN connected to 'Denmark' (78)

C:\ProgramsManual\Expresso>expresso status
VPN connected to 'Denmark' (78)

C:\ProgramsManual\Expresso>expresso status
Reached end of stream but expected 4 more bytes.

I also get the "Reached end of stream but expected 4 more bytes." when issuing disconnect and connect commands, again unpredictably. Sometimes it works, other times it doesn't.

I even got this (!):

C:\ProgramsManual\Expresso>expresso.exe
Reached end of stream but expected 4 more bytes.

So executing expresso.exe with no arguments can even give "Reached end of stream but expected 4 more bytes." But not always. It will work again a few seconds later. And then after a few seconds again not.

This means that Expresso is unreliable as of now. It sometimes works, other times not.

And I really can't find any pattern to it. It's not like it always fails. It fails sometimes, but only sometimes. It's like tossing a coin.

The ExpressVPN GUI client works fine when I interact with it.

Versions:
ExpressVPN client: 10.17.0 (28)
Expresso: 1.3.0
OS: Windows 10 Home (10.0.19043)

I tried restarting the computer, but to no avail. Same problem.
