Confluence server availability

Thomas RAMON

Hi,

Sometimes, my confluence server refuse connection for some workstation, on the same network. For the lucky workstation which it works, the server works great.

It's seems completely random and I don't know where to search to find a solution to this problem.

The server is reachable by a ping even if the server refuse the connection.

Can you help me to resolv it ?

System settings :

Centos 7 - PostgreSQL 9.5 / 9.6

Confluence 6.13.0

Confluence won't do that - a refused connection means the network is not allowing it (it usually means confluence is down or not functioning, but if other people can get to it, that is not the case)

I'm afraid you'll need to do full network debugging - check what is being dropped or refused when the failing machines are trying to reach it.

Hi,

I understand that you're unable to access confluence from some workstations. Are these workstations are windows based? Can you try checking if there are any anti-virus or firewall software installed on those workstations where confluence can't be accessible? If so, try disabling them temporarily and access the confluence. You could also try using different browsers on those workstations to access the confluence.

Shankar

We are checking a possible network configuration issue but I would like to be sure that it's not the server. I don't really know how to check this.

Hi,

I tried with Windows and Ubuntu base systems, IE, Chrome and Mozilla. I disabled firewall for testing but not answer too. That's strange because browsers can reach the server but they print "Connection refused". As Nic said on the top, it's maybe because of the network but I don't really know which logs I can check to be sure it's not the server itself.

If the server is working for some people, but not others, you can be sure the server is not the problem. Because it is working for some people.

It might be something networking related on the server, but Confluence doesn't have anything that would arbitrarily block people (even black lists wouldn't give you this error). So it's a network issue (it might well be on the server - like a firewall that says "only accept packets from these ip addresses", just not Confluence)

You can try a simple telnet command from problematic hosts to verify the connectivity,

>telnet yourconfluserhostorserverip portnumber (ex:- telnet 192.168.1.20 8090)

Do a traceroute on confluence server and check the packets and connectivity.

If you use a proxy server to connect to outside world, try disabling them and check. You can also use command line tools like CURL to verify the status as well.

Hope these help for initial testing.

Thanks for you tips !

I'm now sure it's a network problem

Best regards,
