Mapped Domain shows Too Many Redirects on log in page

Too Many Redirects error shown on page. By itself the it is loading. Domain Mapping settings are set to "domain entered by the user" for Administration and for Login Mapping. When Login Mapping is set to original domain, the error goes away, but it loads which is not preferable URL.

This happens only one mapped domain.

Please advise how to fix Too Many Redirects error on page?
