At first check if the internet is working, for example, open test.inbox.lv
If the internet works, please send us an e-mail (firstname.lastname@example.org, email@example.com) with your IP address and full description of the problem. You can ask your administrator for you IP address or open test.inbox.lv.
Things like that mostly happens in case that there had been some illegal actions from your IP address.
In case you did not find your answer contact us
