Certicate doesn't active after IP change

We changed the IP address of web service with no change in domain. The certificate became inactive even after renew it. It returns this error:

“”
Failed authorization procedure. xxx.com (http-01): urn:ietf:params:acme :error:unauthorized :: The client lacks sufficient authorization :: Invalid resp onse from http://xxx.com/.well-known/acme-challenge/Cuy3W4Y6C81xaXP9joG yZpb-m7OxNIMNj-pxJhBra5w [185.140.12.17]: “<meta http-equiv=“Conten t-Type” content=“text/html; charset=windows-1256”>BNN4-1(1)</h ead><ifra”
