    Dear friends,
    I stumbled upon a strange issue while connecting ESP8266 (WEMOS mini) to CloudMqtt broker service.
    If I use my home network (Wifi) , the ESP8266 is unable to connect to the broker but if the network is changed to a hotspot on my Android device the connection is successful.
    For about 2 years I have used my home network for connecting ESP8266 and did not have any issue.
    Tried with B4R as well as Arduino IDE but nothing works.
    Hence the issue is with my wifi router. But I am unable to resolve it. Can any one please suggest a fix?

    Are you able to connect to CloudMqtt with B4J?

    Yes , that's the strange part. B4A also connects ok.

    Not sure. Are you able to send http requests from the ESP8266?

    Haven't checked it, will do so.
    I think it is a problem with the ISP, because other ISP's work fine. Sorry to bother you!
