The scenario:

DC01 - hosted on premises. Is the first AD server of a domain named: testlab.local
DC02 - hosted on Azure IAAS server. Is joined in the domain testlab.local

When tryting to promote DC02 I am getting the following error message: "Error getting the list of sites from the target enviroment: the user name or password is incorrect"
I am logging in with the right password and username (testlab\administrator).
Ping is succefull to domain and dc01
I am using a site to site vpn to have a connection between azure and on prem.
dcdiag /s:testlab.local gives the following message on DC02:

"Directory Server Diagnosis

Performing initial setup:
[cloudcomputing.local] LDAP bind failed with error 1326,
The user name or password is incorrect.."

dcdiag on DC01 is succesfull. Firewall settings are all open at the router, DC01, DC02 and Azure NSG. Its only open for the vpn tunnel.

Can someone please give me some guidance to troubleshoot this issue?

    So i fixed the issue with authenticating with administrator@Teddy .local instead of TESTLAB\Administrator.

    Might check the account has Domain Admins group membership (or higher) or try with another account.
