There are usually two reasons for this.
1. Your internet service provider has been instructed you block our IP address during a big sports event. To avoid this you should try using a VPN, there are lots of free ones available from the play store or buy entering a play store URL address in Downloader app
Estimated down time 2 hours
2. The server has had to be rebooted or we are updating our systems to add more content. Unfortunately this is a computer and occasionally it will need rebooting and updating.
Estimated down time 30 mins depending on the extent of the updates or maintenance.
You can check for information on the server in the “News and updates” section on our discord support group, which will keep you updated about any situation or updates you need to do to your device.
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.
