What happened:

I can't login to my University Captive Portal, i got a notification from portmaster about it detecting the portal but the logic page fails to open. ( Maybe my UNI is using some bad old type). Then i went to network dashboard and in the Network Noise I can see the that ip is getting blocked . here is the json

First Scenario --> i whitelisted it but then later portmaster later complained that my connection is unsecure. so i deleted the rule. But then later it worked. But then again it did not and i had to whitelist.

I am just confuse on what should i expect and what should happen. I am just going up and down.

What did you expect to happen?:

Captive portal working without doing anything and if i had to whitelist the IP address ( is it safe ) ?

safing / portmaster
