Can't connect to ssh on tryhackme

I connected to tryhackme openvpn and when I tried to connect to ssh on "Breaching Active Directory" room, it tells me

Connection reset by 10.200.89.248 port 22

here is the command:

ssh thm@THMJMP1.za.tryhackme.com

update:

I also run nmap

and apears that ssh is open at port 22

└─$ nmap THMJMP1.za.tryhackme.com
