Can't work with Office Online Server from SharePoint 2019

Can't work with Office Online Server 2016 from SharePoint 2019.
I have Russian SharePoint 2019 Enterprise 16.0.10337.12109 with English Language Pack (with SU KB4486714 16.0.10368.20022)
AND
Office Online Server 16.0.7601.6800.
Web application on SP2019 via HTTP and OOS via HTTP.
On OOS:
New-OfficeWebAppsFarm -InternalURL "http://server1.domain1.local" -AllowHttp -EditingEnabled
On SP2019 (http://server2.domain2.local):
New-SPWOPIBinding -ServerName server1.domain1.local -AllowHTTP
Set-SPWOPIZone -zone "internal-http"
(Get-SPSecurityTokenServiceConfig).AllowOAuthOverHttp
$config = (Get-SPSecurityTokenServiceConfig)
$config.AllowOAuthOverHttp = $true
$config.Update()
(Get-SPSecurityTokenServiceConfig).AllowOAuthOverHttp
Set-OfficeWebAppsFarm -AllowHttpSecureStoreConnections:$true
When I open document library document on SP2019 for OOS, I have error in Microsoft Word Online with correlation id.
On this correlation id I have two interesting messagse in ULS log viewer for domain2\user (not system account on SP2019):
