[SOLVED] Connection Refused to Blynk cloud

Issues and Errors
1

Hi, i’m using the node.js blynk library here and I’m having issues connecting, I’ve tried both cloud.blynk.cc and blynk-cloud.com, and both refuse a connection, I can ping them no problem but the telnet connection gets refused. Any ideas?

Hello. Was it working before? Or this is first setup?

Hey, it was working before, and nothing has been changed to make it stop working on my end.

What IP does ping show?

@Dmitriy, can you comment on this ?

If telnet is refused than problem in closed ports/firewall, no?

I’m getting connection refused from 3 different places, my home PC, my test server and my production server, each with connection refused. As I’ve said, no configurations have changed since it stopped working.

Connection failed: No connection could be made because the target machine actively refused it 46.101.143.225:8441

What exactly command do you run?

Hey. Solved this. Looks like it is my bad after all, I assume there was a change from cloud.blynk.cc to blynk-cloud.com? During my attempted fixes I manually changed the server to blynk-cloud.com but must’ve done it wrong, as resetting the server settings to default fixed the issue. Thanks for all the help though!

Glad it is working now!
