Apparently, this is my problem, in the connection string I used not the method:password, but a base64 string.

gost -L http://:8081 -F ss://base64@127.0.0.1:12345

But I have a feeling we shouldn't panic if we receive incorrect data, or data we can't use.

And maybe we should add the ability to use base64 strings in authorization? I think this link format is often used for connection?
