Soft reset and no connection to host

[luotope]

Hi and thanks for the nice project. I hope I can use it in my sports tracking solution.

I used this code as such in Wemos esp8266, only replaced my SSID and PW. The serial monitor shows soft wdt reset and I located the problem in the following where I added yield() and it fixed the problem:
while (client.available() == 0) { yield(); if (millis() - timeout > 2500) { ...

However, with or without this yield the connection to host fails even before here:
WiFiClientSecure client; const int httpsPort = 443; if (!client.connect(host, httpsPort)) { Serial.println("connection failed"); }

What could be the reason for failing?
Any idea why it cannot make the connection to the host "cloud.internalpositioning.com"?

Output from serial monitor:
Find3 ESP client by DatanoiseTV (WiFi support WITHOUT BLE.)

Thanks again.

Not sure what was the reason but now it works. I just uploaded another https test program which worked fine and then reinstalling this which started to work nice.
