Hello, Mr.Juan
My server can connect remote internet sites via SSH.
I checked my server firewall logs. Then my TCP connection request seems to reset by Airnotifier server.
I was wondering if you could check Airnotifier server firewall log.
Kind regards

Hi,
everythings looks fine and working in our side, I've tested the registration of new devices and it seems to work, can you try in a different server? for example, a local installation in a virtual OS
Regards, Juan
Hello,
Thank you for checking.
I'd like to install different server within a few days.
I'll report the results after I have tried to connect from different server.
Kind regards

Hi, Juan
I have installed another moodle server for test. I tried to connect to Airnotifier server.
My test moodle site displayed error.
I checked using telnet, from my server, to Airnotifier server

Hi,
it seems to be a local problem, can you check this?

Hi, Juan
I checked that.
My server MTU value was default. I have changed MTU value to such as 1500 and 1200.
However, My moodle site displayed error "TCP connection reset by peer".

I have analyzed the packet that sent when I clicked [Request access key] button.
As shown below:
I'd like to install different server with another OS like a ubuntu.
What can I do other.
Kind regards,
