Unable to access to the website interface after update

Install, Configure and Update

Hi guys,
I was unable to access to the web interface after update. i got some messages error after i run this command in the terminal. Does anyone have clue?
ssh -N -f -L localhost:39010:localhost:39010 cryosparc
stty: standard input: Inappropriate ioctl for device
stty: standard input: Inappropriate ioctl for device
kex_exchange_identification: Connection closed by remote host
Connection closed by UNKNOWN port 65535

I checked the ~/.ssh/config and everything looks fine.
Host *
ServerAliveCountMax 4
ServerAliveInterval 15

Host cryosparc
HostName xxxxx
User xxxx
ProxyCommand ssh -q xxxx -W %h:%p

What are the outputs of the commands (on your laptop or desktop computer)?

uname -a
ssh cryosparc uname -a
ssh cryosparc ps -eo pid,ppid,start,cmd | grep cryosparc_

?

Have you investigated this warning or error?

I am not sure what cause this issues. we put our GPU computer in our shool HPC room. typically, these guys not us do the daily maintenance. we also do not have the root permission. when they do the maintenance , they may close some connections. Is that could be the reason?

I am under the impression that the ownership/permissions issue occurs on the “local” computer on which you run the ssh command and, presumably, a web browser. You may want to contact the “local” computer’s administrator for help.

it show same error messages when i run that commands on my local computer. HPC guys told me maintenance is still not done. I guess that could be the reason.

I am now not sure whether this is a problem on the ssh client computer, the jump host and/or the CryoSPARC server.
