<div dir="ltr"><div>Hello,</div><div><br></div><div>This is more likely to be a Horizon bug than an issue with Kolla itself, since Kolla doesn't change much from the default configuration.</div><div><br></div><div>You should check Horizon logs in /var/log/kolla/horizon to find the error. I would also encourage you to upgrade to a more recent release, since Train has been marked as End of Life in Kolla recently.</div><div><br></div><div>Cheers,</div><div>Pierre Riteau (priteau)</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, 9 Sept 2022 at 15:41, Albert Braden <<a href="mailto:ozzzo@yahoo.com">ozzzo@yahoo.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;border-left-color:rgb(204,204,204);padding-left:1ex">We're running kolla train and we're seeing an apparent bug when we try to add or remove security groups on a port. We see error "Failed to update port <ID>". It works fine in CLI; we only see this in Horizon. Is this a known bug, or are we doing something wrong?<br>
