Help Error 1103

[Carmen Torrano]

Hello
I am a teacher in Spain. I have a problem because I cannot connect the phone with de AppInventor.
The error that the phone shows when I type in the code is Error 1103: Unable to post or put the text
I am sorry for my English.
Thank you
Carmen

This appears to be a school network firewall issue. error 1103 means there is no internet connection. Can you connect the phone using a non-school network; for example at home?    If you can connect at home, the issue is probably the firewall.

I assume you followed the usb instructions here  http://appinventor.mit.edu/explore/ai2/setup-device-usb.html  .   Did you install the required USB drivers to your Windows PC?    Did you change the Android Setting in your phone in the developer section to allow  USB Debugging?

If this is a school network issue, ports 8001 or 8004 might be blocked preventing communication between the PC and phone.  General instructions for school networks are here:  

• SCHOOL IT/NETWORK ADMINS: Information specific to school networks (also helpful for conferences and hotel situations)   and   Troubleshooting: Help with saving and using apps, Fixing common errors, etc.  

Does that help?

Regards,

Steve
