So, since end of march 2026 i've been trying to fix my arma reforger, everytime i download one or more of the mods listed i get the Unknown error 0,
I've tried multiple fixes;
Deleting mods from Arma Reforger
Reinstalling all mods (atleast 5x times)
Deleting the addons folder (atleast 5x times)
Trying another storage unit (nvme ssd)
Deleting download cache on steam
Deleting onedrive completely from my desktop and delete all things related to onedrive
Reinstalling Arma Reforger twice
Verifying integrity of game files on steam off arma reforger (3x)
I've got enough storage on both ssd's (both above 400gb free)
Deleting leftovers from recycle bin (mods)
Restarting PC (+20x)
Starting Arma Reforger as Admin didnt work
Also doing Launch options on steam didnt work, heres the thing i used in my launch option:
ArmaReforgerSteam.exe -addonDownloadDir "C:\Program Files (x86)\Steam\steamapps\common\Arma Reforger\addons"
i also tried trying it without the launch option but didnt work either.
- - Giving my PC wifi trough mobile hotspot from my phone which didnt work
- - My PC is connected to LAN the whole time since my motherboard doesnt have an Wifi adapter
- - I cannot use an VPN to download the mods because i dont know how to do that if it even helps
One thing i want to mention is that my wifi speed is very slow, 1,2mb/s (10-12mbit/s) at best, i cannot change that because i am still waiting for fiber in my street.
I also noticed that most of the mods are above 100mb, i dont know but it could be this but i dont know so i ask u guys for help.
I really need ur help guys, hope we can fix this asap.
Thanks!
