Can not open a terminal session via the gui

Hello Everybody,
I logged onto my production version of ondemand and found I could no longer open a terminal session.
The error is:
Your connection to the remote server has been terminated.

When I check the log: at /var/log/ondemand-nginx/myuser/error.log I get the following:

I have not touch this server to make changes in a long time. What could be causing this error? I do have a dev enironment and that does not exibit the same error.
Thank you,

I think you need an apache update.

Hi,
I have a prod server and a dev server. It does not happen on the dev server. And both apache versions are the same:
ondemand-apache-3.1.6-1.el9.x86_64

Not the ondemand-apache package, but the actual apache httpd server package - httpd.

Hi,

It’s at httpd-2.4.57-8.el9.x86_64 and so is the dev server.

Even so, is there any update available for it on the production server?

Hi.

So the solution was to downgrade OOD to 3.1.7 on my RHEL 9.3 system.
