Thanks Mike! Unfortunately, upgrading is not an option since its a really
loaded enterprise device. The interesting part is that there is a
similarly set up websockets vip (plain old server i think .net) that is
working on the same device.

We'll work with our network folks to find other devices with newer
software we can use.

Would appreciate if anyone has other ideas?

Regards,
Anthony

We are running 11.4 and 11.6. I'd give an upgrade a try before digging
too much deeper.

Does any one have any experience configuring F5 load balancers in front
of the CF routers? We have configured F5 and app https and cf push requests
are working fine. However, the connectivity with loggregator is not
working. Taking a look at the documentation, it requires "websocket
support" on the load balancer. We've done the configuration specified here:

https://support.f5.com/kb/en-us/solutions/public/14000/800/sol14814.html

With the following irule basically, applying the default TCP profile if
it detects websocket traffic:

when HTTP_REQUEST {
if { [string tolower [HTTP::header Upgrade]] contains "websocket" }{
HTTP::disable
}
}

However, we are running into errors. Doing `cf logs myapp1` yields:

Error dialing loggregator server: read tcp <ip redacted>:443: connection
reset by peer.
Please ask your Cloud Foundry Operator to check the platform
configuration (loggregator endpoint is wss://loggregator.<sys domain
redacted>:443).

Does anyone have a clue?

Thanks!
