not able to access f5 via ssh and gui

Hello

anybody have same issue that acces f5 via ssh and gui failed, telnet to port 443 and 22 success

log during ssh

kex_exchange_identification: Connection closed by remote host

hi, can you send verbose log for ssh connection from client side? e.g. “ssh -l <username> <f5 device> -vv” It seems that kex are changed after upgrade (did you upgrade the system?) and there is no match between client and server side.

i did not upgrade system, few days ago i can access via gui and ssh

the problem solved after change boot location by console
