Have you any idea ?

FYI i've tried to change the ip in ManiaControl settings with my server ip and with the "local" ip 127.0.0.1 and i^ve the same result

Did you check which ports are already in use on your system?
If the ports are already occupied, this would explain the error.

[ybconcept]

Thank you for your reply.

The port 5000 seem free before allocated in the pterodactyl panel.

I’ve try with the 5001 and i’ve the same error

[TMarc]

There are other ports as well, what about the port for the database server?

Did you check if the Maniaplanet dedicated is basically running alone by itself, without controller?

[ybconcept]

I just try with the port 27031 (used for another remote control on the past) and i've the same result.

The ManiaPlanet Dedicated works good. I can play on

[TMarc]

what about that allowremote setting in the cfg? it is set to false, this could also simply block connections to the management port.

[ybconcept]

It's set on True

Code: Select all

		<xmlrpc_port>27031</xmlrpc_port>
		<xmlrpc_allowremote>true</xmlrpc_allowremote>

[TMarc]

Not that one.

This here in your dedicated cfg.txt

Code: Select all

<xmlrpc_port>5000</xmlrpc_port>
<xmlrpc_allowremote>False</xmlrpc_allowremote>

[ybconcept]

i've change from false to true and try again. Same result on the two cases

[reaby]

<force_ip_address>.........</force_ip_address>

i think you're forced the ip address for the server ?
then there's no loopback adapter available for localhost

dedicated_cfg.txt

Code: Select all

<force_ip_address>*hostIPaddress*</force_ip_address>
<xmlrpc_port>5000</xmlrpc_port>
<xmlrpc_allowremote>*hostIPaddress*</xmlrpc_allowremote>

you could as well put allowremote to True, but that would open it for all incoming connections, if so, make sure you have strong password.
so better to keep it "localhost" only, when you're more free to choose weak ones as well

maniacontrol config

Code: Select all

<host>*hostIPaddress*</host>
<port>5000</port>

should work if i'm not totally wrong.
