B4R Question Why strange strings ?

[peacemaker]

Hi, All

1) I used the ESPUI interface lib in one project - and the web-interface was working the same way in AP-WiFi-mode and in WiFi-client mode. It was no HTTP data exchange in this first project
2) Now this interface code module was copied into another project, this project works with a server by HTTP-requests.
In AP-mode via http://192.168.4.1 URL the web-interface is fully OK, as programmed.
But when ESP32 is connected to a WiFi router as client, http://192.168.1.53, and started to work with the server - the web-interface is...:


JSON strings of the HTTP requests.
Why ?
And if to refresh the webpage - the connection indicator is flickering, "connected\disconnected", trash...
