Hi,
Just can’t seen to get a successful connection & auth to blynk-cloud.com.
Hardware is a D1 Mini based on 8266, wifi on my local network connected through broadband provider, Latest Blynk Libraries.
As you can see via the code I’ve tried a few different connection options. Connecting wifi via Blynk.connectWiFi I can see I successfully get wifi connected and see a valid IP, but then Blynk.connect is not successful.
Using Blynk.begin just appears to hang and not progress any further with the code.
I’ve tried ports 8080 and 80, with no success
I can successfully ping blynk-cloud.com. telnet blynk-cloud.com 80 appears to connect OK but I only get a blank screen and flashing cursor at the terminal so I’m not 100% sure that is the behaviour that is expected.
All help appreciated.
