For some reason I have installed a fivem server using the TXADMIN installer and everything was fine until I had to modify the server.cfg file after that the server stopped appearing in the lists and also sometimes appears as OFFLINE and after a few minutes it appears ONLINE again…in addition to that depending on the player they see it OFFLINE or ONLINE.

It is very strange, I checked using the IP and PORT to see the info.json and everything was correct. In addition to this, I used a website to identify if port 30120 is open and indeed it is. I need immediate help because this problem has never happened to me before.

I forgot to add that I tried to perform a VANILLA installation (without using tx-admin) and in the same way the server does not appear in the lists.

While the server is not listed, you should check the page for the server ID on https://keymaster.fivem.net/, mainly the ‘Public Listing’ section.
