Proxy and web cache

Hello, I changed IP address of my web page and now discovered the issue: traffic with turned on CloudFare Proxy DNS is tranfered to non existing admin panel page of web page. I had purgeed all cache but problem is still.
Admin panel without Proxy option is working and is acceseble without problems…

Have You some advice or experience?

And with :grey: DNS Only (after waiting the five minutes to take effect), works correctly?

yes, using DNS only, I can reach admin panel. I suppose it is about caching…

Have You some suggestions about that?
