After installing Oxide, I get the following errors:
Fallback handler could not load library /home/rustserver/serverfiles/RustDedicated_Data/MonoBleedingEdge/x86_64/data-0x557170f5dca0.so Fallback handler could not load library /home/rustserver/serverfiles/RustDedicated_Data/MonoBleedingEdge/x86_64/data-0x557171f5e6f0.so

But after 5 minutes, the server starts. When I try to install plugins, it says: Could not load plugin 'NoGreen' (no plugin found with that file name)

this error are not related to anything, standard error from rust... oxide are updated? o.version return?

The oxide reacts in the console, but now I understand. In Russia, they blocked the oxide.
