p0tter119 Posted February 27 Share Posted February 27 Same for me, 1.12.2 works fine but 1.20.1s forges just don't open and i wanted to play with my friend so i would need to install a server. If anybody has a server instalation pls send it to me. Btw a simple fix for this if you don't care for server hosting is installing it through curse forges launcher then forge works just fine but i need this server install Quote Link to comment Share on other sites More sharing options...
Paint_Ninja Posted February 27 Share Posted February 27 This is a known issue caused by Mojang abruptly removing one of their domain names. A fix is underway.

Paint_Ninja Posted February 27 Share Posted February 27 Download a fresh copy of the installer and it should be fixed. https://discord.com/channels/1129059589325852724/1129077934330744882/1212138871907684382 Quote Official Forge Discord server | Support FAQ for players Link to comment Share on other sites More sharing options...
