Cannot install mods on dedicated server

Hey guys! I was trying to get a couple of mods installed on my dedicated server using the Mod Manager v3.0.3 and after successfully adding my server by entering the SFTP credentials I always get this error when installing/removing mods on it:

failed to resolve lockfile: failed to write lockfile: failed writing lockfile: failed to create file: sftp: "performing OPEN gave the following error: invalid handle mode specific" (SSH_FX_OP_UNSUPPORTED)

failed to resolve lockfile: failed to write lockfile: failed writing lockfile: failed to create file: sftp: "performing OPEN gave the following error: invalid handle mode specific" (SSH_FX_OP_UNSUPPORTED)

Any ideas? Thanks in advance 🙂

what server provider are you using? there is a chance they don't allow the required ftp operations

I'm using shockbyte

You just mentioned the name of a hosting provider (shockbyte) that either does NOT support or has incomplete support for modded Satisfactory dedicated servers! Check the list here to learn more. https://docs.ficsit.app/satisfactory-modding/latest/ForUsers/DedicatedServerSetup.html#UnsupportedHosting -# Rule logic: https://regex101.com/r/rKL6oV/ -# Responding to unsupporteddedicatedserverhost triggered by @nuuunu

do you know which FTP operations are required by SMM so I can confirm if they’re supported?

Robb•3w ago

as the bot replied above, that provider is known to not work. you can try contacting their support so they can work on fixing it I don't know them offhand, but the tool is open source, and we can work with you and their support team to get that working assuming their support actually responds
