Your information is protected by SSL.
No. 1569 Re: Re: Open socket to https site 2018-03-05

I am using the ezTCP device as a client.
In the mean time I have changed the setting of our https server for not doing certificate sending and I am now able to create a connection with the server.
However when I send a HTTP GET request, I only receive the HTTP header, but not the requested data. When I do the same request on a PC to the same server, it is working (HTTP header + data)

After some time when the server closes the connection, I get a "NO CARRIER" response from the module.

If I do the same with SSL disabled and connect to the same server, it is working.

Any idee what could be the cause of this?
