DNS, domain, firewall issue on port 8090

Question

I have a server running Jira and Confluence.

Jira @ http://jira.domain.com:8080 Confluence @ http://wiki.domain.com:8090

I can reach the applications from the server, from my home pc. But on my work pc only Jira is accessible. What am I missing??

On the server:

Jira:

http://jira.domain.com:8080 WORKS
http://localhost:8080 WORKS

Confluence:

http://wiki.domain.com:8090 WORKS
http://localhost:8090 WORKS

Home PC:

Jira:

http://jira.domain.com:8080 WORKS

Confluence

http://wiki.domain.com:8090 WORKS

Work PC:

Jira:

http://jira.domain.com:8080 WORKS

Confluence

http://wiki.domain.com:8090  !!!! DOES NOT WORK !!!!

What do you mean by does not work - what error messages do you get ? — user9517, Nov 05 '12 at 11:29
It doesn't resolve the host name to ip. Default Chrome error message: "Cannot connect to wiki.domain.com:8090" — Ropstah, Nov 05 '12 at 12:54
Maybe a proxy on your work PC. Could be an automatically detected proxy. — Laurentiu Roescu, Nov 05 '12 at 14:57
8090 is the port I use for websockets. Took me a long time to realise that it's generally blocked at various network points. I had to proxy my link. — rockstardev, Nov 20 '21 at 12:56

Sounds like an ACL somewhere. Most likely a firewall rule or restriction in .htaccess or similar.

I thought firewall also, however it's not on the server side (home pc works) and my work pc has port 8090 allowed as inbound port... – Ropstah Nov 05 '12 at 12:13
Your work PC's firewall doesn't factor in there. The return traffic wouldn't be on 8090. There's probably a hardware firewall in place somewhere that is blocking the traffic. – MDMarra Nov 05 '12 at 15:14

You don't give any information about the network topology work-->server<--home but they are unlikely to take the same route so make absolutely sure that there isn't some device between work and the server that is blocking port.

If it's not a firewall blocking the route to the port then check that the hostname is resolving correctly from your work PC use

dig  wiki.domain.com   (linux)

or

nslookup wiki.domain.com   (windows)

If the DNS is OK then I'm out other than to check your hosts file.

Resolving works fine. It is the port that is blocked by our company. Thanks. — Ropstah, Nov 05 '12 at 14:57
