so im hosting on my computer with java 1.8 and go to run the server, starts fine but no matter what modpack as long as its 1.12.2 all my friends time out. I just got new wifi and its wayyy better and my pc is fine it can run it so i was wondering if it was an issue with java. please help. (edit) so just extra info the forge is forge-1.12.2-184.108.40.20605-universal speeds are 10 megabytes (not bits) for upload and 80 megabytes on download i also have 48 gigabytes of ram an intel i7 and java is 1.8 the lastest downloadable 1.8 i think (edit2) also this is ONLY 1.12.2 modpacks servers on lower versions run perfect my friends are at 5 bars lag free. Another note 1.12.2 VANILLA servers work fine so its something with forge i think.
