Eccentric Cone

This is a problem I have seen on the forums, but solutions I have seen do not work for me.

I am trying to insert a bend at the line made by "cut-extrude 5", and get "Non Linear edge is invalid" error.

For reference, I have attached a file of a concentric pipe where I had no issues.

Any tips/advice would be much appreciated.
