We have been observing below error in Zscaler Client Connector in one the Ubuntu workstation.
Endpoint FW/AV Error
I have checked articles related to Zscaler Process exclusions, but did not found any thing related to Ubuntu/Linux.
Can any one help ?
The Endpoint FW/AV Error error typically means that Zscaler Client Connector cannot communicate with itself and an AV or host-based Firewall product is blocking this communication. May I ask are you using ZCC for ZIA, ZPA or both?
We are using ZCC for ZIA only.
If you are using third-party AV or Firewall, try allowlisting the following processes:
Allowlist the entire path of the following files:
Thanks for your reply.
But we are seeing this in only 1 PC. though the same AV is installed in all the rest other PCs.
Maybe there is another process/service that listen on TCP 9000 on that specific client, and you can use:
C:>netstat -o -q -n | find “:9000”
Process ID will be in the 5th column and then you use Task Manager | Details tab to find which process it may be.
TCP 9000 is the default port that Client Connector is using, and can be adjusted here: Zscaler Mobile Portal | Administration | Client Connector Support | Endpoint Integration, and it will be applied on all installs, so be careful.
We have some lab equipment software that rely on TCP 9000, so moved to TCP 9001.
We are seeing this issue in Ubuntu OS Machine.
Sorry, but I guess it applies on any supported OS, I mean; that another service/process is listening on TCP 9000.
I’ve checked it. There is no other process/service which is listening on TCP 9000.
