Wifi captive portal never working

[dragolollo]

Hi all, I'm new to the forum, nice to meet you all!
I have a big problem: I can't open any captive portal (wifi login page) of any network; it always shows an error of connection closed. Until a few days ago everything was working good. Now I'm forced to use all the time websites like neverssl.com to avoid https. Does anyone know how can I fix this issue? I guess something in the settings is changed since this happens for any network with a captive portal. I have a Xiaomi Mi 10T Pro.
Thank you
