Why was netfile rejected?

[new-2018]

In all the years I have used TT I have never had issue with NETFILE.

Today all three of the returns I wanted to file were rejected.

No specific cause noted. Just the 5 tries warning and check your software.

I tried 2x so still in limit. I check TT says no updates to process.

The Canada Revenue Agency's electronic services are currently unavailable. This includes the NETFILE and ReFile.  If you experience issues with any of these services, please try again later.

I tried twice to netfile Doris Return with the log in security code BC7BX3K4 . Why was it rejected 2x?
