The problem with Steam link, when trying to connect a line to an existing account, writes: identification error.
Error! Your account is already a Steam ID.
Before the appearance of the problem, the CPU was replaced and Windows was reinstalled. After that, I noticed this problem.
The name in the FAF was changed from Bpamapb to LastKick, but this did not help.
