In reply to Jeff Trionfante. Never mind. Finally figured out the web user interface comes directly from the sketch and not from some outside site.

In reply to SERKAN TOPALOGLU. Assign a static IP address to your ESP in your WiFi modem. So, whenever ESP will try to connect to modem, it will connect to the same IP address every time. There no need to change anything in esp code.

Thanks for your tutorial. Everything worked exactly as described. Very clear and understandable. However, if I close the web interface page after the first use and then try to reopen it again even after a minute or two, I get a timeout or just a blank page. It will sometimes work again after several hours, but again only for one time. I can send multiple messages during that one time with no problem. Hope this makes sense. Any advise or suggestions would be greatly appreciated.

I implemented this solution with my ESP8266-12E and a 4 segment MAX7219 HiLetgo, both from Amazon. The latest library file MD_MAX72xx.h from github no longer needs manual editing. Just edit the Arduino code to #define the correct model. It would be easy to have these options already offered in the .ino code as comments. I used: #define HARDWARE_TYPE MD_MAX72XX::FC16_HW. Thanks for posting this.
