Invalid IP Adress (from Client but already played on the Server)
A Client has already played on my Server after the first installation a fwe days ago with Version 1.14.1.5. Also with Version 1.14.20.1 is not working
On the same Day the Client played and after a reconnection it said Invalid Ip Adress. After a restart and a change of my DynDns Adress it is still not working.
The other Players dont have that problem. And the Problem Client also can join to other Server.
Environment
The Server is running Ubuntu 18.04 LTS with Pterodactyl Egg. A Docker image Gameserverpanel.

Resolution: Unresolved → Invalid

Hi S W,
This sounds like a DNS issue on the client end, have you asked the user to try the IP instead of the DynDNS address?
DNS updates can take up to 24 hours to replicate globally to every DNS resolver, its possible this one user was just using one that hadnt updated yet.

Ok i will let him try it again but what is strange for that when my IP address didnt change during the day he suddendly couldnt join any more.
Thanks! Let us know how it goes!
Could you clarify what that error (the screenshot) says in English, might also help get to the bottom of it.
The Picture says Invalid IP-Address.
The client tried it again without entering the Ip address and it worked. It was only when it happened during the day when on my side nothing changed with the DNS settings.
Thanks for the support
Thats great to hear!
Could a mod please close this issue.
