I've asked them before to unblock DNS domain (thanks to earlier suggestion here on the forum from Leszek), then they did put me through to another division, and asked me to write an e-mail about it to their address.
Thats what i got in reply:
"Serwery DNS 194.204.159.1, 194.204.152.34 zwracają prawidłowo nazwę na podawana nazwę."
Translation:
DNS Servers 194.204.159.1, 194.204.152.34 does return the correct name.
Below that, they attached a log from their diagnostics - I attached it below as text.
But probably its not DNS fault. Should I query them again? Maybe We could arrange Orange and Remote Utilities technical support team e-mail exchange? It would be easier for all of us, to get all the information needed.
