DNS switching back and forth between CF and old DNS host

I accidentally revereted nameservers to my dns host which is the same as my domain registrar in Poland. I wanted to switch to CF back by specifying nameservers in appropriate inputs on the registrar platform. After a while, my registrar’s service says that domain is no longer maintained at their site and point to the CF nameservers. So that’s good. However I keep checking the dns lookup tool (https://dnschecker.org/) and the name servers and all the dns records keep switching back and forth between my old registrar and CF. It looks like some loop that doesnt resolve. The domain is fedit.pl.

It looks OK across public resolvers…

On DNS checker I see all are ok as well. Maybe you looked too soon after changing the nameservers. Things seem to have settled now.

It looks like they only sitch back and forth in Google DNS servers. Others look fine

@sjr yeah, it looks ok but the website still doesnt work;

When you paste 45.151.126.119:8080 where I serve the front, it works. So it’s the DNS issue. But i have no idea where. Here: DNS Lookup - Check All DNS Records for Any Domain it looks like all is good except when you swtich to google servers. Then it just switches back and forth between my old registrar and CF.

It connects on http://fedit.pl:8080 (to a blank page, same as your IP address). If you just want to use fedit.pl you need to set an origin rule to tell Cloudflare your server is on port 8080…

You have changed your nameservers away from Cloudflare now…

Yes. I revereted back for debugging. I will switch later again. Looks all good now, just having issues with DNS on my local PC.
