She had better luck at the Coupe Banque Nationale in Québec, where she won her first round singles match against Alla Kudryavtseva before losing to eventual champion Alison Van Uytvanck, in a match which was riddled with errors from both players. She also played doubles, with Julia Glushko, meeting the fourth seeds Naomi Broady and Asia Muhammad in the first round. The first set in this match was over very quickly as Erakovic and Glushko managed to hold serve only once, but the second was much tighter, with breaks of service traded before going to a tie-break. A double-fault at a crucial time cost them momentum when leading, and Broady and Muhammad eventually prevailed in two sets. Possibly the lowest point of her recent career followed as she moved to an ITF tournament in Albuquerque, New Mexico.

She then had four weeks off, before returning in an ITF tournament in Macon, Georgia. She lost in the first round in both singles and doubles, and followed that up with another first-round loss two weeks later in Waco, Texas, Eikeri again proving her nemesis. In that year, her level dropped to such an extent that her poor run to end the North American ITF Circuit left her ranked outside the top 200 for the first time in seven years. Her doubles ranking had started the year on the back foot in any case, due to a lack of play in 2016. Unable to find a partner at any tournament until halfway through the year, where she and Chang Kai-chen went quite well in England, she again finished the year without a partner. Her ranking slid all
