Not really - only when the password is wrong or the wifi has gone down. Do other devices connect to it in the same area? You could try an SSID scanner to measure signal strength and check what band it's running on and then google your model of phone to see if people are having issues with that particular band. But most phones should be pretty much fine with anything - it's usualy devices like HRMs and turbos and stuff that are picky about wifi bands.
You haven't just turned off wifi or something silly? Have you tried connecting to any other wifi? Can you hotspot?
Anyone ever have the issue where they can't get their android phone connected to WiFi? Happened twice in the last week with my new pixel. Both BT WiFi routers at 2 different houses. Been googling it but nothing has fixed it yet
