                    on wine vUbuntu 5.0-3ubuntu1 throws 12006

Hi there,

I stumbled upon this issue when HeidiSQL's update checker began to fail to
contact the mother ship.

I then had a very long back and forth with a troll but that ended when the main
developer of HeidiSQl stepped in and I decided to replicate the update check
code under Lazarus.

I used fpcupdeluxe to install Lazarus and copied the offending code and had a
go.

I can report that I've tried to access:

1. https://www.heidisql.com/updatecheck.php?r=6119&bits=64
2. http://www.heidisql.com/updatecheck.php?r=6119&bits=64
3. ftp://www.heidisql.com/updatecheck.php?r=6119&bits=64 (Yes in desperation)
4. I now need to test if the "file:///" SCHEMA doesn't trip this wire

All of the above have always given me a GetLastError()==12006

As stated on summary:

- wininet.dll version is 8.00.7601.17601 as reported from Sysinternals's
sigcheck
- wine --version return "wine-5.0 (Ubuntu 5.0-3ubuntu1)"
- My system is Ubuntu 20.10 64b with wine64 and wine32 installed and updated as
of 2020/11/11
- Tested with InternetOpenURL()
- Tested with InternetOpenURLA() (I really don't know what I'm doing here)

If you really insist I can probably conjure up some C code to test this.
At the moment I only have Free Pascal code that I can provide.

Cheers,
Gus
