After deactivating VPN and ad blocker, then rebooting, my iPhone will recognize a known good WiFi network and let me log in, but it immediately drops the connection. Any thoughts on resolving this? Data charges are piling up.
Settings - General - Reset - Reset Network Settings
(Are you using the Cloudflare 1.1.1.1 VPN?)
Might have to remove a Profile.
I’m thinking the same as @MacExpert
It’s probably the vpn profile that is still there, it can’t connect to it anymore so drops the connection.
