[verbal canyon]

Hello,
I just installed pterodactyl and when trying to install a server, it fails.

I get an "Connection reseted by peer" and a "Url not specified"

container@pterodactyl~ Server marked as offline...

curl: try 'curl --help' or 'curl --manual' for more information
running: curl -o server.jar 
curl: (2) no URL specified

Install Complete

afterwards it still tries to start and gives an "Error: Unable to access jarfile server.jar"

upload a jar file in the files

it worked.

I just want it to download it automaticaly when i install it

[tranquil gull]

That would work, but it wouldn't permanently fix it

[merry lintel]

i think the issue is with the network and firewall config of the server itself

[tranquil gull]

I guess so

could be this the problemm?
