Currently, IOTA is in maintenance on our platform due to a problem on the IOTA network.
This means that customers cannot buy or sell IOTA at this point until the issue is resolved. Users of the Trinity wallet are advised not to open or use the wallet until further notice.
Update from IOTA 17/02/2020:
We have released an updated version of Trinity which allows you to check your balance and transactions. Please download this newest version of Trinity here and install it over your old version: https://github.com/iotaledger/trinity-wallet/releases/tag/desktop-1.4.2
Please use the guide on installing the new Trinity release here: https://status.iota.org/
