Hi David,

You could change the TLS minimum version just before your http request call:  
SET DATABASE PARAMETER(Min TLS version;TLSv1_1)
Its worth a try, but for me it did not work.

There seems to be a bug in 4D v16R6 (and v17), which makes certain https sites 
(like https://www.google.com) unreachable from within 4D and only happens in 
certain situations. But I don't have details.

I've been hit by this issue a few weeks ago. I recently did a new test and 
suddenly all was working fine again. No changes in my network config. ISP?.

My findings are:
- macOS (two different versions 10.11.x and 10.13.x) on two different machines 
(iMac MacBook Air) in the same network
- 4D v 16R6 and v17ß
- rebooting machine did not help
- curl from terminal was OK
- 4D Windows in Parallels on the iMac was also working fine
- MacBook in different network was working fine again
- iMac connected through iPhone G4 hotspot was working fine too

4D Tech assistance confirmed the issue was reproduced by QA and is under study 
by Engineering.
Lets hope they find a quick fix.

HTH
Koen
