Servers are not showing on server list

for long time i have proble with my servers (all on one dedicated server), they are not listen on rust server list ;/ sometimes they are visable but only sometimes ;/ is there a way to fix it? is it possible that my IP is blacklisted? (some other custom servers that i know have that same problem). 

I have few IPs blocked in iptables, but they are chines bots i think :P 

Server can be hidden in several cases:
  • server ip was banned by Facepunch
  • server ping is very high (more 500)
  • server is not responding (offline or under ddos attack)
1. how can i check this?
2. nope... ping is ok,
3. nope... online, all, and no ddos

btw some users can find it, some not :D i think there is problem with server list in game...

its heavy too. Full updating takes a lot of time
Same here... I am from Bulgaria. If host server with 20 ping people form Bulgaria will find it.
If host from Paris they have 55ping like Playing in Rustafied EU servers. Good host and No lag but... Missing from the list. 
Yesterday one guy did stream and wasnt able to find the server. He only found old one hosted as Informaion server (20ping as i said) and read the info and joined inside new one this way.
Another guy did stream and found it when he lives in AE and got 150 ping...
There must be other problems with the stupid list. I do not know why when server has good stable  around 55 ping for my players and its not blacklisted or DDOS-ed do not show.
i bought for test small VPS server in my country and installed rust server with that same config that now is not on list and it is working. 
I have found other server that use dedicated server in that same location that my and this server is not showing on list too... this rust server list is strange :)
Server browser is broken since the 6 June 2019 update (because Garry had to go and mess it up last month). Here in Brazil I can see servers in South America and... South Africa (?!?!?). Can't even see my own server hosted in New York.

So it is a Rust problem nothing we can do?
Yea looks like so...
I watch my servers not discovered by players. New players join inside one sevrers full with admin abuse because i have 8 regular ppl but the servers with 3ppl (all admins) is listed better because i host bulgarian server from paris (paid host that do not have our small country) and other one is located in my country. Eh quality is not important just you can see and korean servers with fake pop and 400 ping better than sevrers which you look for.

The fact is that I had this server for 6 mouth, had around 80 ppl, then last mouth I god a surgery and closed it.

I came back now and I can see it in my cronology, some player can find it, but me and I really lots of player can not event see it...

So I took anather machine to test the problem, only intalled the game and changed the name of the server, same problem....

I use kimsufi, that is hosted in France, never had a problem since now (to be honest since 30 days ago as I closed it).

I contacted the support and they told me: your kind of server would need the port opening in the game firewall...well...never had to do that in the past...I contacted the provider in order to do so...waiting to see if this work

Don't bother contacting Facepunch's support. Report this as a bug (F7 in game or link below), so it goes straight to the devs. I had my players do it, but the more people complain, the better.

Don't really think the problem is your host....
