[BUG] Firefox can’t establish a connection to the server at ws://myip:8080/rconsole.

Hello,

I have a fresh installation of eXist-db 5.2. running on CentOs 7. When I open the Monex application I'm asked for the admin password; after successfully logging in I get a ' Alert! Connection to server failed. Retrying ... ' message at the top of the page, and I have these errors in the console:

Firefox can’t establish a connection to the server at ws://myip:8080/rconsole. exadmin.js:231:25

Interestingly, when I click on instances.xml within the 'remote monitoring' page, I get this message from eXide:

Failed to load document /db/apps/monex/instances.xml: 400 Bad Request
exerr:ERROR Permission denied to read + document: instances.xml [at line 40, column 14]

I can open the instances.xml file via oXygen (xmlrpc connection). The owner of that file is admin, group dba.

I see that @joewiz writes that Monex 2.x and eXist-db 5.x should work well together (#92 (comment)). I'm using Monex 2.1.1, and I still get the issue mentioned in #92 .

[lguariento]

OK, this is weird. I downgraded, as suggested in #92 , to Monex 0.9.16, which doesn't work out of the box with eXist-db 5.2.0 since it gives this error:

<exception>
<path>/db/apps/monex/modules/view.xql</path>
<message>
err:XPST0003 The ':=' notation is no longer accepted in map expressions: use ':' instead. [at line 21, column 33]
</message>
</exception>

Therefore I updated it, via the package manager, from 0.9.16 back to 2.1.1, and now it works a expected. It might be a workaround useful to others.
