Different site, different time and same Cloudflare problems

Maybe year ago i changed nameservers on my site and it broke site with redirects.
Now, today i did same thing with different site and first it didnt make changes in loading page but few hours later i cannot access site because of too many redirects.

I cannot detect problem.
If someone has some info, i would gladly listen

Fyi i panicked and changed nameserver like it was before

too many redirects on cloudflare is usually due to ssl settings set to flexible, try disabling cloudlfare ssl or use strict setting.

I went for good old: setting everything to normal.
I know cloudflare would help my site security wise and maybe speed, but this is second time it fkcs up my page.
My site wasnt active whole day because of that
But thanks for advice, i will maybe implement this in future
