Could fortinet be a problem to connecting with blynk cloud?

I am not getting a permanent solution for my project. I don’t know why this is not connecting to my network.

Help me!!

Hello. Have you read http://docs.blynk.cc/#troubleshooting ?

Yeah, i did read that but my problem is , why blynk cloud is not connecting with ip.

My serial monitor is showing

[0] Blynk v0.3.4
[0] Getting IP…
[1251] My IP: 172.16.6.196
[5001] Connecting to blynk-cloud.com:8442
[30767] Connecting to blynk-cloud.com:8442
[56024] Connecting to blynk-cloud.com:8442
[81026] Connecting to blynk-cloud.com:8442

and so on…

what is the problem ?
sometimes without doing anything it shows some different IP starts with 10.42.0.78 and with this IP everything is fine.
And serial monitor shows

Ready ping.

help me what to do?? please.

So what is result? Does telnet works for you? Are you sure your router doesn’t block Blynk ports? Does everything work with Local Blynk Server?

Yes, telnet is working and as i told you everything is fine with IP 10.48.0.72 but this IP comes very rarely.
