i try to connect to an web api from my netdcu-a5.
I have one testing environment and another productive environment which use different SSL certificates.
On the testing environment everything works fine, communication from device to API looks good.
On the productive environment I get on each request (HttpSendRequest(...)) Error 12157 (ERROR_INTERNET_SECURITY_CHANNEL_ERROR). Wininet documentation says "The application experienced an internal error loading the SSL libraries" on this error.
I guess it is a problem with not installed ssl certificates / trusted authorities.
I can access both APIs from my desktop browser without any problems.
Now my question:
- How can I check if the needed trusted authority is installed on my device?
- How can I add new trusted authorities?
- Any other idea what is the cause for this problem?
Thanks in advance and best regards
