Plugin on server side rejects valid certificate

[bigli0n]

I have the server configured using v2ray-plugin in tls (websocket) mode using a self-signed cert and key. On the Android client, using certRaw it works perfectly. Trying the same config on a linux client results in the "remote error bad certificate" error, despite it being the exact same certificate. I have tried both downloading the original cert to the client via scp, and copy-pasting it, and the result is the same. Why is this happening and how to fix?
