Everything i do is from Curseforge app installed from its site.
Two days ago there were no problems or issues, i did not modify anything at all in Curseforge app or whatever, in vanilla from Curseforge no problem when i connect to my LAN world with my other pc, but todays since the whole day, even on an empty modpack, can't connect to LAN or with essentials mod, which says "router not found", i repeat, this does not appen in vanilla even on the app, but as i create a modpack, even empty, that problem appears, which never happened before.
I deleted and reinstalled the app, restarted the modem even if my wifi works perfectly, and still there, i even tried to disable temp firewall shit and nothing
