Cause of self-check error after changing the IP address of the controlled end

A controlled server updates the IP address of the server in the normal way. The controlled license is reinstalled and a running license is obtained. The a record of the DNS of the controlled domain name is also changed, however, the following errors still occur during self-check:

Msxml3.dll error '80072ee2'

The operation timed out

/INC-freehost-function/freehostfunction. asp, row 254

It is very likely that your controlled end is accessed through the domain name. After your IP address is changed, the domain name will take a general time to update. Therefore, when you perform self-check, you still need to access the old IP address. This error will occur, and the DNS will be normal after a period of time.

Alternatively, you can create a new controlled end and assign a new domain name. The new domain name can be used immediately when it points directly to the new IP address.
