I'm not sure whether this is a Tramp bug. eshell tries to parse
something in its buffer which it believes it shall be a variable.

Maybe you check, what's there at position 1801 in your *eshell* buffer?

Your user name seems to be "address@hidden". This is visible in the
prompt. Maybe eshell tries to expand "$eR" as variable?

You could add the user name to your ~/.ssh/config. In this case, you
don't need to specify it in the Tramp file name.
