Cannot open "/proc/sys/net/ipv4/route/flush": Read-only file system

[MirolHusni]

My connection successfully authenticated but then stuck at the Connect Banner and showing above error message.

Can u help me fix this?

Thanks in advance

I ran into that error before. I think I remember the solution being to just ignore it as it was cosmetic and wasn't actually causing any issues. Do you have any problems with the connection?

• https://gitlab.com/openconnect/openconnect/-/issues/354

I did implement the advice in that serverfault post to install the latest version of the script.

Can you rebuild the image from the latest git commit and see if it goes away? Or is it still happening for you with the latest?

I have this all the time and it doesn't cause any problems.
