Modpack version
E6 any.

Describe the bug
On installation of the E6 server, people get an error that forge-NONE-NONE is not found and the install/start keeps looping without doing anything.

Cause
The serverstarter.jar fails to resolve the given installerUrl properly by not following redirects, the given installerUrl results in a "Moved permanently" error, which can get resolved by using a download method that follows HTTP Redirects.

This causes the download of the forge installer to fail, and consequently causes the actual install to fail.

Either the URL needs to be updated to the new location (not ideal) or the serverstarter.jar needs to be changed to actually honour HTTP Redirects.

As reference the same happens with E2E as per EnigmaticaModpacks/Enigmatica2Expert#1909 and the Unix shell script if you do not have wget installed. Curl requires the -L flag to resolve HTTP Redirects, otherwise the download will fail, the install will fail, and the script will give useless errors.

Thanks for the report.

Curl already uses the -L flag:

I have updated the forge link in the server-setup-config.yaml, that should resolve this issue. I was however not able to reproduce it.

Hmm. That's a commit from the 14th, so that'd be.. 0.5.6. So then the only thing left is E2E, I guess, E6 is fixed.

Fixed in-dev for E2E :)
