I'm using Clarion 8 + NT9.31 and got Let's Encrypt certificate with 3rd party software verified by DNS. I'm using dynamic DNS because this is a POC. Didn't touch in any dll or component from NT.
Browsers can access the secure server example based on Example 9 (Always TLS) and open https pages without complaint.
I have a customer that wants his Web site on Wix to send form data to this Clarion server and should be https using node module fetch on Wix side.
The problem is that fetch commando does not have access to Clarion server giving timeout of 14 seconds. Browsers pointing to dynamic DNS can access it.
I testes with all 4 test tools mentioned in NT documentation but Sophos cannot connect to server and times out, Htbridge's SSLScan says that server don't have SSL/TLS, SSLLab cannot connect to server. SSLScan.exe (very old) can identify the certificate and show it's informations.
Tried without any success disabling Firewall or changing NT configurations.
Plesase, could any one give me directions?
