Issue with Web.Get - But WebViewer works (linking to an Arduino)

Thanks for both answer! @vknow360: I tried with Google.com and the Web1 receive the info perfectly. So the issue is on WebServer side. @Juan_Antonio: I will try that, but in the last test I remove the if to answer date info, always. And it didn't work. My ESP8266: ESP01S.

Guide on the ESP8266-01:

Examples with the ESP8266-01. Wifi. LED on/off. Arduino. Standalone. MQTT

The ESP8266 has a lot of variety of models... https://www.researchgate.net/figure/Variation-of-ESP8266-modules_fig1_332527943 https://blog.squix.org/2015/03/esp8266-module-comparison-esp-01-esp-05.html The best known are the ESP8266-01 and the ESP8266-12. We can find the ESP8266-12 on the NodeMCU board. [nodemcu2] But I prefer the Wemos D1 R2 board because it has the look and size of an Arduino UNO.
