Hey ! Found something ! bFkpnWq0NTx8PmXmyo1jQVsmW6h was actually a piece of my password, between a @ and a #. It seams that this caused an error in the rsync address generation, I just changed it and everything working.
I tried to update KSP (not Steam) 1.1 to 1.1.1 using the patcher (both with launcher and directly) but I got an error:
rsync: getaddrinfo: bfkpnwq0ntx8pmxmyo1jqvsmw6h 873: Name or service not known
rsync error: error in socket IO (code 10) at clientserver.c(125) [Receiver=3.1.2]
Any ideas ?
