Hello

during instance startup we are getting an error for the instance.

lxc container is used for the instance. It is also worth noting that there is a high number of access to the instance through API calls.

any thoughts about why this error is generated.

Thank you

Hey, sorry you are facing an issue! Is the LXC Container running NGINX? I don’t think this error log is enough to debug the issue, would you please share your NGINX config settings?

If there’s a problem with the configuration it could cause this issue. And I will make sure to ask for support. Thank you!

Hello Al-Gassim

I made an upgrade and it was resolved.

Many thanks
