My WiFi connection is saved and secure - but not connected.

[AC Question]

Recently I stayed away from my house for a night in an area without any WiFi. On the day before, my internet connection worked perfectly fine and there were no issues. However, as soon as I came back my internet connection has simply "Saved, secured" but not able to connect. I have used the forget function several times as well as restarted my phone and I have no idea what else it could be. Does anybody have an idea?

Have you tried to reset the router?
