Troubleshooting Zgemma, VU+ or any Enigma2 device. 

There are only 5 possible reasons your service could be down or not letting you log in.
Please check them in the order.
Username and Password
The most likely reason it won't let you login is you entered the details incorrectly. Please be careful with capital i's and lower case L's, in a lot of fonts they look the same, capital O's and the zero can look slimier, and Upper case and lower case K's.
All test work 100% of the time and the login details have been copied and pasted direct from the server so they are not wrong.
Please do not email saying the detail don't work, they do.
Does the device have a
working internet connection?
If you are not seeing the channels and have a red light next to in Jedi, then either the details are entered wrong, or the device has no internet.
If this isn't the first time setting it up then it is most likely the internet connection.
Check the Ethernet cable is connected, or check the WiFi dongle is connected, then run the to network check in menu/systems/network/device setup/network test.
Then try resetting the router and device.
Subscription Expiry
Has you subscription expired. Please check back in your email for the date you was sent the subscription and how long you paid for. If this was a test it expired 24 hours from when you was emailed it. If it has expired and you wish to continue please purchase a package from this website, or another free test.
IP Lock
Your device will be IP locked to the device you last logged in to.
It it possible to move your subscription to a different device but it will only refresh the IP address every 15 mins.
It will allow you to login, but no channels will play in this time. 
If you wish to use more than one device you should consider buying a second line.
The Server is Down
The server maybe down. There are usually two reasons for this your internet service provider has been instructed to block our IP address during a big sports event.
For this you should try using a VPN like Liberty Shield.
Estimated down time 2 hours
The server has had to be rebooted. Unfortunately this is a computer and occasionally it will need rebooting.
Estimated down time 30 mins.
You can check for information on the server in the forum on this website, or on our twitter page, I will keep them updated.
 Please try not to email in this situation it only delays in further, and I can not offer you a solution other then waiting patiently.
