Registered FOP2 Failes to connect

[nicolas]

You should be looking at some kind of firewall.antivirus blocking access to port tcp/4445. Or you might want to try with a different browser. Did you try with google chrome?

[yahdie]

I tried Chrome, IE & Firefox. The anti-virus is the same on all machines MS Security Essentials

[nicolas]

open the javascript console in chrome and look at the output, it will help you see what is going on.

Same as the previous user:
Used to work.
Stopped working.
No network issues (telnet connects fine).

IE 7 seems to work
IE 8 Connecting 1 and never moves
Firefox (windows and linux): Connecting 1 2 3 4 5....
Chrome Linux: SNAP! (no idea if this worked before)

Here's a dump from the console in firefox

Maybe you are not experiencing the same as other users, it might seems so, but it most probably not the same as IE7 worked for you. If that is the case, then adobe flash is not having issues, and your problems might be related to websockets. There is an article in www.fop2.com/blog talking about issues with firefox and secure websockets (that are not supported in fop 2.26, but are in 2.27). So, most probably disabling websockets in /var/www/html/fop2/js/presence.js will fix your issue with firefox and chrome. Upgrading to the latest fop2 version, and enabling the server secure certificates if you access fop2 via https will make it work with websockets on both browsers (but be advised that configuring those certs is not that easy, and making the browsers accept a self signed websocket certificate is difficult as they do not work transparently as when simply accessing a secure website).

AstLinux developers put together a nice summary page on making fop2/ssl work:

Actually, IE10 is not working with FOP2; no browsers on this PC allow me to connect. Other PCs at that location are logged into FOP2 without issues.

If you want to use latest browser versions, you must use latest fop2 versions. Or you can disable websockets in fop2 in /var/www/html/fop2/js/presence.js

Sorry for the late reply.

Ok, disabled the websockets.
Now I'm stuck on "trying to connect: 1"

Tracing network communication I can see replies coming in (Follow TCP stream in Wireshark):
<msg data="GENERAL|contexto|1|" />.{ 'btn': '0', 'cmd': 'key', 'data': '****************', 'slot': '' }.{ 'btn': '0@GENERAL', 'cmd': 'version', 'data': '2.11', 'slot': '' }.<msg data="1|ping||" />.{ 'btn': '0', 'cmd': 'pong', 'data': '0', 'slot': '' }.<msg data="1|ping||" />.{ 'btn': '0', 'cmd': 'pong', 'data': '0', 'slot': '' }.

Server in debug mode says it sends them:

10.1.60.6 <= <msg data="GENERAL|contexto|1|" />
10.1.60.6 => { 'btn': '0', 'cmd': 'key', 'data': '*****************', 'slot': '' }
10.1.60.6 => { 'btn': '0@GENERAL', 'cmd': 'version', 'data': '2.11', 'slot': '' }

10.1.60.6 <= <msg data="1|ping||" />
10.1.60.6 => { 'btn': '0', 'cmd': 'pong', 'data': '0', 'slot': '' }
10.1.60.6 <= <msg data="1|ping||" />
10.1.60.6 => { 'btn': '0', 'cmd': 'pong', 'data': '0', 'slot': '' }

JS console says it does not get any "pong" replies:

Are you using FOP 2.11? You should upgrade if you want to use modern/recent OS and Browsers. In version 2.11 websockets cannot be disabled on the fop2 server side, for example, etc.

Question: where did you run wireshark? on the desktop machine? on the server? somewhere in between?

Question: Can you connect from other machines? This thread was hijacked with many people thinking they have the same problem but it is not the same problem. For example, using FOP 2.11 with the latest chrome is a recipe for problems, you MUST upgrade fop2 as well as you upgraded your browser.

And finally, if the connection is established, as it seems it is, but then the application is tuck on "Connection to server X", it most probably means you have some non ASCII characters in your button labels, and the button config file or mysql for autoconfiguration is not sending the data encoded in UTF8. Again, this is NOT RELATED at all with the original post on this thread.

Somehow I managed to get a mix of 2.11 and 2.26 in place :oops: My apologies
Getting everything to 2.26 solved the issue.

On the desktop machine.

Question: Can you connect from other machines? This thread was hijacked with many people thinking they have the same problem but it is not the same problem. For example, using FOP 2.11 with the latest chrome is a recipe for problems, you MUST upgrade fop2 as well as you upgraded your browser.

The same effects occured everywhere as it was server related. However, Chromium on a Linux desktop still goes "Snap!" immediately (can't even log in). This is not an issue for me (Chromium is not used at my customer's site).

And finally, if the connection is established, as it seems it is, but then the application is tuck on "Connection to server X", it most probably means you have some non ASCII characters in your button labels, and the button config file or mysql for autoconfiguration is not sending the data encoded in UTF8. Again, this is NOT RELATED at all with the original post on this thread.

This was not an issue, there are no non ASCII characters (or all is UTF8 as I don't ever accept any other encoding wherever I see it, UTF8 rulez).
