Goodmorning,

I would like to do HTTPS calls to get information from a customer. HTTP calls works without an issue. HTTPS calls will not work. I use the LHTTP library. I use a s7-1516 cpu.

In the library the TCON block gives error 80E1 and with other certificate 80E4. 

Does anyone now what i do wrong? Maybe an working example would be perfect. 

I also tested with postman. 'https://postman-echo.com/get?foo1=bar1&foo2=bar2'. HTTP works HTTPS not.

Thanks for the advice.

Hello MathiasN12345

The datatype for certificates should be explained in Chapter 4.7 in the manual of the library:

And there is also a link to the general description for certificates in TIA:

(I have not done https with S71500 yet so unfortunately no experience...)

Bye Murof
