E OS 1.20 or higher has null as captive portal http, https, fallback and other fallback

I expected to find e os links to captive portal but appearantly the e os captive portal links are no longer working when i tried them on my lineage os phone :
https://e.foundation/net_204 and 204.ecloud.global

and when i checked thecaptive portal links that come default on my e os 1.21 phone I got null for all 4 http, https, fallback and other fallback.

should they be changed to anything else?
I used these on my lineage phone after the e os links I mentioned did not work:
http://captiveportal.kuketz.de

I have no idea about them but should be better than default google captive portal

Please let me know if E os has new captive portal links and if I should change the null values on my e OS
