Unable to install mods

When downloading mods with my ethernet plugged in I get the error message “

download failed clientexception: HVV NA-GALACTIC ASSAULT-YAVIN connection closed while receiving data, uri=https://dl.kyber.gg/mod-storage/bfplus_v10_1b.zip”
and with ethernet unplugged on full internet connection, it doesn’t work at all. Please help idk what is happening. Antivirus exceptions are active, and the game is owned legitimately
