Hi everyone
I hope someone can help me with a rather puzzling issue.
We have a website, collaborative.eversheds-sutherland.com 213.212.88.203 which users can connect but experience very slow performance when navigating around the site. This only occurs when they are on the network. Performance when accessed from home or another non-network source is absolutely fine.
From what I can tell, traffic leaves our network via the firewall (bypassing the proxy). This proxy override has also been enabled on Group Policy for this website. However, the puzzling thing is that I’m still seeing active sessions for this website on the Bluecoat Proxy Gateway. I believe the traffic is coming back through the Proxy but I can’t see why.
Gateway details:
ProxySG 810-10 SGOS 6.5.3.6 Proxy Edition
Is there anything I can check on the Bluecoat? Like I say connectivity is there but the website performance is very slow. When users use the developer tools in the browser to inspect the site, they commonly see the following errors:
ERR_TUNNEL_CONNECTION_FAILED
CORS Policy Error
I’ve looked up both of these errors and they both point to a proxy issue but I cannot work out what it could be. I’ve attached a screenshot which shows the active sessions currently on the BC Gateway. The Gateway IP is 10.20.48.100 but each different office has it’s own BC Proxy server that does it’s own web filtering. The one on screenshot is from the London office.
I’d appreciate any assistance as this is proving to be a huge issue for me.
Many thanks
B
