Until now everything is working. I am able to make both http post, and mqtt connection.
I checked and mine esp32 firmware version is 2.4.0. So,Is it because of this lower version, I had to do some hack around for ssl connection?
Below is the part of workaround I coded to make it work with hydroserver.

Before opening a tcp connection, the Socket Receiving Mode should be made to 1 (passive mode). I have no idea why it works only while doing this. But it works.

But I am struggling to use this to connect to mqtt broker.

I have been trying this codebase or even the one with tinygsm library but nothing works. Is there any pre-configuration that is needed to be done?

So, how do I even do POST request to server running on the web? Are there any Wifi modules that are alternative to Xbee that supports SecureClient?

Does secure client really works for DigiXbee S6b?

I used TinyGSM directly and got into this problem. I was deploying broker locally,, the code on the inside check for dns lookup.. Currently I commented this code out and tinygsm works.

This is what my full code looks without tinygsm:
