Respect SETTINGS_HEADER_TABLE_SIZE http2 setting

[Yurunsoft]

My nginx config:

upstream grpcServer {
    server host.docker.internal:13009;
    keepalive 3600;
}

server { 
    listen       8890 http2;

    access_log  /var/log/nginx/test.access.log  main;
    error_log  /var/log/nginx/test.error.log  error;

    add_header 'Access-Control-Allow-Origin' '*';
    add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
    add_header 'Access-Control-Allow-Headers' 'authorization,DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';

    # grpc
    location ~* ^/(.+)\.(.+)/(.+)$ {
		grpc_set_header Host $host;
		grpc_set_header X-Real-IP $remote_addr;
		grpc_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
		grpc_socket_keepalive on;
		proxy_next_upstream off;
        grpc_pass grpc://grpcServer;
    }

    location / {
        index index.html index.htm;
        root /var/www/;
    }

    gzip on;
    gzip_min_length 1k;
    gzip_comp_level 2;
    gzip_types text/plain application/javascript application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png;
    gzip_vary on;
}

Error log:
