Friend Spawning underground and nothing is moving

I made a server and when my friend entered the server she spawned underground, and when she got out nothing moved, I tried giving her operator privileges but that did not work.

Solution 1:

"Nothing moving" means that the network connection between your friend and the server is way, way too slow to play.

If you're running this server over your home network, there could be all kinds of reasons why it's slow, but the most likely is that the upstream connection (how data goes to the Internet, as opposed to downloading from it) provided by your Internet Service Provider is low-bandwidth and/or high-latency. This is typically the case on home networks unless you pay for more expensive service, because "normal" home Internet usage downloads a lot of data but sends very, very little. Either of high-latency or low-bandwidth will make it hard or impossible for the server to send updates to your friend in real-time; it's like trying to drink through a tiny straw when your friend's Minecraft needs to slurp from a firehose to run properly.

Solution 2:

Their are a few variables that may affect this.

If you are running the server from a home network, it is most likely that either yours or her internet connection is not fast enough. If she is able to play on majority of other server perfectly fine then it is most likely your internet connection. What is causing this problem is known as the upload speed which refers to sending information from your network. I recommend doing a speed test and if your upload rate is less than 1Mbps, don't bother hosting a server. If she can't play any other server than it is most likely her end that is having download issues.

The other problem may be lack of memory to run the server. Generally a server requires a fair bit of memory to run smoothly especially with plugins installed. For a 2 person server I personally recommend at least 1GB of RAM dedicate to the server. If you are running a x86 OS I recommend upgrading to x64 as it allows you to allocate more RAM (x86 OS == 1GB MAX dedicated RAM). This can be expensive however and you must be sure that your computer can handle x64. If it can't, it is highly likely that your computer does not meet the requirements to run a server. Also, if it is possible, don't run the server on the same computer as you are playing minecraft on. If you decide to allocate more RAM, your computer may lag and be impossible to play minecraft. This won't be the case if you keep the RAM the same as when you normally play Minecraft as single player runs an internal server while you play anyway.

In conclusion it is generally the Memory allocated to the server and the upload speed of your network to the internet that causes no movement to be seen on the clients computer.
