Internet Error: -4 under any non-system shell when using ssh on Android 4.2.2

[MegaCron]

Hi all.

I get the following error under any non-system shell when using ssh on Android 4.2.2

Error: Internet Error: -4 when talking to: ... (any site, http, https)

The site can be any - it is both http and https. I got this error on standalone 4.3 bash and on bash 4.4 from entware.

Linux localhost 3.4.5 #1 SMP PREEMPT Thu Mar 27 16:19:17 CST 2014 armv7l GNU/Linux Xidel 0.9.9 (20200201.7173.9d381d1545ec) dropbear from SSHDroid 2.1.0

P.S. I can use strace on this device

[benibela]

-4 means no connection. Perhaps there is a firewall or no internet permission?

In strace there should be socket(AF_INET, SOCK_STREAM, IPPROTO_TCP), sendto... and recvfrom... (at least on linux)

[MegaCron]

Perhaps there is a firewall or no internet permission?

There is no problem with internet access. Both under sh and under bash

Under bash, I did not find strings containing a "socket"

[MegaCron]

Can anybody help?

[benibela]

It is too weird

Looks like the sh worked, the server answer ("HTTP/1.1 200 OK\r\nDate: Fri, 13 M". ) is there. But otherwise I see no difference between the sh and bash log, except for the timezones in the sh log. But the timezones should not matter for HTTP.

Are there different environment variables (env) set in sh and bash?

[MegaCron]

Sorry for the long delay with my reply. Damn coronavirus.

LD_LIBRARY_PATH can affect a lot of things. Try to run it with LD_LIBRARY_PATH=/vendor/lib:/system/lib xidel

As benibela said:

This does not work :( Again the same error :(

After a long time, I updated (20200201.7173.9d381d1545ec) xidel to 20210620.7908.1f19357dcdf2 and the problem is gone, but there were problems with https requests > _ <
