Yes I have been across this. The problem is that we are using a Bearer token that need to be refresh after some time. Using this creates a static token that is only generate a boot time. I created a custom AddSolrNet with takes the httpClient as a parameter

   private static ISolrConnection CreateAutoSolrConnection(IServiceProvider serviceProvider,
        Func<IServiceProvider, string> urlRetriever, Action<SolrNetOptions> setupAction, HttpClient httpClient)
    {
        var solrUrl = urlRetriever(serviceProvider);
        if (string.IsNullOrWhiteSpace(solrUrl)) throw new ArgumentNullException(nameof(solrUrl));

        if (httpClient == null)
        {
            var connection = new AutoSolrConnection(solrUrl);
            if (setupAction == null) return connection;

            // Allow for custom headers to be injected.
            var options = new SolrNetOptions(connection.HttpClient);
            setupAction(options);
            return connection;
        }
        else
        {
            return new AutoSolrConnection(solrUrl, httpClient);
        }
    }
