KTS block Microsoft Edge connection after connecting public network, even after switching private network

earlier in the morning I use public wifi because I were in public area; and it wenr smoothly without a problem, and later on the afternoon when I went back home connecting to my own wifi; I can't seems to accees and always ended up with ERR_CONNECTION_RESET (as seen as screenshot below), I tried troubleshoot the connnection but seems no to fail; even tho I can use other browser such as Chrome just fine. and then I tried to exit KTS and it fix the problem (screenshot below).

Is there away I can revert this issue?

thanks in advance
