Solange has canceled her New Year's Eve performance at Afropunk in Johannesburg, South Africa due to health issues.

The singer opened up about her diagnosis with autonomic disorder, an illness that affects parts of the nervous system.

“The past five months I have been quietly treating, and working through an Autonomic Disorder. It been a journey that hasn’t been easy on me,” she wrote on Instagram. “It’s a complicated diagnoses , and I’m still learning so much myself.”

Solange, who has been heavy on the festival circuit over the past year, since the release of her critically-acclaimed album, A Seat At The Table, was slated to be the headliner for SA's Afropunk, alongside Anderson. Paak. As of now, there's no word on who will replace Solange on the bill.

"I can’t put into words how saddened and sorry I am that I am unable to perform for you guys this NYE, there is simply no other place I wanted to be than there with my family to bring in 2018 with you.......but I give you my ABSOLUTE WORD I will come back with AfroPunk and deliver this performance.....as it is so extremely important to me to connect with the people who have so closely inspired me in so many ways,"" Solange wrote.
