Hotspot keeps turning off after Nougat update

[AC Question]

I live in Sweden and have got Nougat update some months back. But since then, the hotspot turns itself off ( OR maybe wifi turns itself ON) automatically. This keeps happening always and I have to manually turn off wifi everytime.

I have tried repartiioning the cache but it does not help. I am using stock android. Never rooted the phone.
