Thank you for your message. Your question was answered via email: your master account was set to 1kbit/2kbit which is extremely low bandwidth and was causing issues. We recommend to all of our hotspot operators to use unlimited bandwidth for master accounts.
If you have any additional questions or technical issues with the service please let us know in order to support you.
Regards,
