Server hostname and description not saving after server restart. These are the commands I am using to set the hostname and description and to save it:
server.hostname "inserthere"
server.description "inserthere"
global.writecfg

It might have to do with command lines or config files, but I don't understand why it's getting reset. I'm renting my server through Pingperfect.com
Most server providers have similar setups for managing servers but I was hoping I could get suggestions/help on how to fix this.

These parameters must be added into commandline arguments

You can add those as command-line arguments or under the server.cfg file, the writecfg command only saves owners/moderators and bans.

Here is the config file I setup, however the server name now shows up as "My untitled rust server" in the rust server browser.
server/Pingperfect/cfg/server.cfg  :  -batchmode -nographics +server.ip 107.181.173.69 +server.port 28215 -maxplayers 60 +server.identity "facepunchdev" +server.hostname "Frosted 5x|Powersmelt|NoBp|Icraft" +server.description "Bgrade, instant craft, powersmelt, nobp, license, tp, sethome, and more!" +server.seed 4356 +server.level "Procedural Map" +server.worldsize 4000 +fps.limit 30 +server.maxplayers 60 +server.saveinterval 300 +datadir "serverdata/" +rcon.ip 107.181.173.69 +rcon.port 5305 +rcon.web 1 +rcon.password "lupsing" -logFile "log.txt"

The command line manager in the web browser for the server is setup as this:

-batchmode -nographics +server.ip 107.181.173.69 +server.port 28215 -maxplayers 60 +server.identity "facepunchdev" +server.seed 4356 +server.level "Procedural Map" +server.worldsize 4000 +fps.limit 30 +server.maxplayers 60 +datadir "serverdata/" +rcon.ip 107.181.173.69 +rcon.port 5305 +rcon.web 1 +rcon.password "xxxx" -logFile "log.txt"

There is only a few options for me to change with it: identity, seed, servermap, size, fps and Rcon Password

Custom command options:

cfg
	Descriptionc
	FPS
	headerc
	Identity
	Server Map
	Rcon Password
	seed
	+server.levelurl
	Server Name
	Url
	worldsize

But with this, the server still doesn't show up on the rust server lists

My server provider was useless

You cannot have - and + prefixing the commands in server.cfg, it's just one command per line. Things such as -nographics, -batchmode, -logfile, rcon settings. do not go under server.cfg either they only work in the command-line. "datadir" also doesn't exist that I am aware of.

Is there an example of what the config file should look like? 
From what you're saying, i'm thinking that the config file should look like this: 
hostname "xxx"
description "xxx" 
without the prefixes.


Also,
Yeah the server provider I'm using doesn't appear to be setup very well... any reccomendations to rent from?

Wulf said about no "+" or "-" prefixes, "server." is a part of a command itself.

server.hostname "Something"
server.description "Another thing"

Most prefixes are optional though in Rust, so "hostname" and "server.hostname" would work usually, but I'd generally stick to the full command/setting.

But "server." and such are still part of the command as I said.
