Exchane 2016 hybrid with Microsoft 365 - refused to connect issue

Hi,

looks like I did everything to integrate Exchange 2016 and Microsoft 365.
1. All Virtual directory URLs are available from internet
https://ex01..com.ua/ecp , https://ex01..com.ua/owa, https://autodiscover.***.com.ua/ ... powershell
2. The certificate has been assigned

I`m getting error
ex01.***.com.ua refused to connect.

@DenisPasternak-3587

I have helped you removed the domain name from original post.

Try to log on your Exchange server and do this action on your Exchange server, using "https://localhost/ecp" to login ECP from IE. If you still cannot access it, you can download HCW from this link directly: https://aka.ms/HybridWizard (Download with IE)

Please make sure all needed port open for Exchange online: Hybrid deployment protocols, ports, and endpoints
