Hello

tip: check in iis manager ecp application http redirect settings.

Check your NAT rules on the firewall, or examine settings on the load balancer.  Internal DNS must be correct since it works internally.  But what about external DNS?

Hi,

Generally, status 301 means that the resource (page) is moved permanently to a new location. Please refer to Sneff_Gabor's suggetsion to check the Redirect setting s for OWA and ECP in IIS manager.

Additionally, please provide more information about your issue and collect any error logs for further troubleshooting.

Regards,
