Samsung S10 disconnecting from Wifi

What phone do you have? Samsung S10

What plan are you on? My choice + 6GB

Does your plan include data, or just talk & text? yes

Issue Description

Phone keeps disconnecting from Wifi. Connect and then disconnects. If I go to a link it says “blocked”.
I have reset my router and talked to my internet provider and all is good. Happens at other wifi connects at work as well.
Have turned my phone on and off multiple times.
Have repaired to wifi multiple times.
Been happening for approximately 2 plus weeks.

While gives some good ideas doesn’t give the details of “how” … like how do you actually get to the “clear chache” area.
