Re: We're sorry, the Canada Revenue Agency was una...


CRA is the one who gives the 5 attempts on Netfiling errors then blocks the terminal. It could be as simple as a spelling mistake in the name or address. If the information provided doesn't match or if this is the first time to file a return to CRA you will not be able to Netfile.


Unfortunately, without knowing the reason form CRA, we cannot diagnose the issue.


I hope this was helpful.
