Unable to connect to Blynk

[raccon82]

Hi guys. I’m pretty new to Blynk and I’m having one problem with Ethernet shield.

The error is as follow.

[0] Blynk v0.3.3
[0] Getting IP…

I’m unable to connect to the blynk server in this way. Anyway I’m trying out this in my campus thus unable to configure any router or so.

Thanks!

Hello. Please switch to 0.3.4. Also please try to investigate possible problem. Here basic instructions - http://docs.blynk.cc/#troubleshooting

Hi,

I’ve tried with 0.3.4 but still couldn’t solve the issue.

Did you try the troubleshooting steps as suggested by @Dmitriy? Could you post the results of that?

Did you check your router settings? Does 8442 port opened? Firewall?

[raccon82]

I’m in a campus and thus theres no way I can check with the router setting. Firewall is off as well.

Here comes the werid thing. All this time, I’m connecting the blynk server in my lab’s ethernet port which i’m unable to connect up. But once I’ve change to another location which is in the staff room, I’m able to connect up. I guess there’s some port forwarding undone in the lab or so.

Anyway I’m getting a wifi shield to try it out.

Did you figure this out? I also am behind a campus network. I know enough about networking but once it goes to the campus level I’m not so sure.
