Hello again,
in my previous post I mentioned upgrade was solution to us but there were some background circumstances and later we figured out real solution in our case:
in IIS > ibmcognos (under Default Web Site) > Authentication > Windows Authentication > Providers: at the moment we have not configured Negotiate so we removed it, there is only NTLM left
After we did that new Edge chromium passes authentication using sso.
Chromium uses its own weights and I guess it is not accepting sort list of available providers on the server:
