I suppose that Power BI Report Server and underlying SQL Server are on the same VM / server, so networking isn't an issue here.

Did you make any changes to default name of Power BI databases "ReportServer" and "ReportServerTempDB"?

From one of my troubleshootings, I was adviced by MS support engineers to modify config file to log more details. It might help you find more details in your logs as well:

C:\Program Files\Microsoft Power BI Report Server\PBIRS\ReportServer\bin\ReportingServicesService.exe.config

<system.diagnostics>

    <switches>

      <add name="DefaultTraceSwitch" value="4" />

    </switches>

  </system.diagnostics>

  <RStrace>

    <add name="FileName" value="ReportServerService_" />

    <add name="FileSizeLimitMb" value="32" />

    <add name="KeepFilesForDays" value="14" />

    <add name="Prefix" value="appdomain, tid, time" />

    <add name="TraceListeners" value="file" />

    <add name="TraceFileMode" value="unique" />

    <add name="HttpTraceFileName" value="ReportServerService_HTTP_" /> 

    <add name="HttpTraceSwitches" value="date,time, clientip,username,serverip,serverport,host,method,uristem,uriquery,protocolstatus,bytesreceived,timetaken,protocolversion,useragent,cookiereceived,cookiesent,referrer" />
