11 months ago I realized problem is not about 2 client. Problem is about client. When I try to POST json request to my server it returns this 403 error, but not reqbin.com gives any error, even it works perfect. Do you have any idea @govorox @RobertByrnes

11 months ago 2 things I'd check. You are using the same gsm layer for both clients. This could make state tracking very tricky for the application, and also make for a broken state. First of all make the 2 stacks have a unique set of objects for simplicity, safety, and clarity. Also, 403 forbidden, yes is client error but also check the path you are trying to access is correct and is available to your client from the web servers side ....
Also given you are using 2 clients for the one modem you should be fine be ensure you are calling client.stop() between the request to clean up the state. You might also want to look into doing something similar with the gsm transport layer. Not sure exactly what TinyGsm offers for this vut probably something there...

11 months ago @RobertByrnes first of all thank you for your respond. I made a test with this repo : https://github.com/Samorange1/Connect-ESP32-to-Firebase-via-GSM and it worked. I can send data to firebase with this method. But when I change code to sending json request to my server it gives 403 error, each time even if connects endpoint. I dont know how to make things works but I'm trying to send json data. Actually my last php code works well with reqbin.com but returns 403 with sim800l request.
Its like something refuses arduino request

11 months ago Another thing I've done before is to build the request in Postman. Then you have visibility over exactly which headers you are sending and can view the full requests and responses in the console. Can help

11 months ago @RobertByrnes I'm just trying Postman, its also working with postman requests, and not suspicious headers there. I changed body types to x-www-form-urlencoded in reqbin, it returns same 403 forbidden, switching back application/json made things work again.
I confused about is my headers wrong or another permission problem exist. It's not make sense for me.

?>may it about file_get_contents() func?

11 months ago and also in postman, changing json to xml mades return 403

11 months ago its my arduino side serial monitor response
and this is reqbin request (its working)
do you see any mistake?

commented
11 months ago The only thing that jumps out at me is that you have no space after the : in your Content-Type and Content-Length headers...
Also double check you are happy sending from esp32 as text/plain to php and then from php as application/json. Should be fine...

11 months ago @RobertByrnes Didn't worked unfortunatelly.
But its my own vds server, do you have any advice to change some settings about security or permission?

11 months ago @RobertByrnes I found what causes 403 error, its line which includes file_get_contents() func in my php code. I changed this and it worked.

Hello everyone,
I'm trying to getting datas from a client and then sending data to another client. The probem is, one client needs ssl/tls connection (which is no problem I can connect and take datas) and other client is using http port:80 (probllem is here).
When I tried to connect and send data individually to this http server its okay everythings work. But when I try with other ssl/tls cleint I think there is some kind of conflict.
this is my structure of clients.
and the POST response from database_client:
I guess its no problem with server I can send data induvidually, I also tested with https://reqbin.com. there is no problem.
But when I use with other client, its not working.
I am open to any suggestion.
