Captive Portal issue
Hi Team,
My wide AP ISP uses a captive portal where I can only use the internet after logging in with my creds successfully. Something like a public wifi would do but on a slightly larger scale.
The captive portal gway IP is 172.16.0.1 and when I enter it on my browser, it redirects to portal: login.sync. Or I can do it the other way around and it will direct me to portal nonetheless.
After installing the NextDNS package on luci and configuring it, I am really happy that everything works well except, whenever I restart my router, I will need to disable the NextDNS service to allow me to login to captive portal because it just wouldnt open it. This is the error message that comes up.
DNS_PROBE_FINISHED_NXDOMAIN
I have gone through some discussions here and outside to find a way around it without success.
Rebind protection has been toggled off with no effect.
Heres my nextdns config
config nextdns 'main'
option setup_router '1'
option report_client_info '1'
option log_queries '0'
option bogus_priv '0'
option auto_activate '1'
option max_ttl '0s'
option cache_size '10MB'
option detect_captive_portals '1'
option use_hosts '1'
option timeout '5s'
list listen 'localhost:53'
option cache_max_age '0s'
option control '/var/run/nextdns.sock'
option hardened_privacy '1'
option config '??????'
option log_query '0'
option enabled '1'
Any help is really appreciated. Thank you.

Assuming that's the full portal login domain, you either need to whitelist portal.login.sync or create a DNS rewrite for the IP address

I too am having this issues with such captive portals as flights and hotels. How can I determine what the private IP is so I can create a rewrite?
