Hi everyone,
 I have followed the documentation to install i2b2 1.8.2 on our test VM.
We upgraded from 1.8.1a.
Wildfly is up and running and I cannot see any errors in the server.log (there are lots of warnings).
We created local credentials to test this. Those credentials were working before the upgrade (we created the credentials, tested login, upgraded - in that order :) )
Now when I try to login with my local account, I get this pop up alert with 
"There is a problem contacting the server!"
We are on Ubuntu 22. 
thank you!
Vidhya

Good morning, everyone!
This could be a follow up of a sort to my previous post. We have set up our production i2b2 instance with Shibboleth login.
I'm now not focusing on the test instance. I have upgraded our prod instance to 1.8.2, copied i2b2_config_domains.json from the working webclient back up.
But I'm seeing this " "There is a problem contacting the server!" error. The Shib login is successful.
I don't even see any calls to proxy.php 
Wildfly seems to running fine. No errors, but lots of warnings.
If anyone has ideas, I'd love to get some help. thanks!

For anyone else facing this issue, this is how I resolved it.
We were running Wildfly on port 19090, as opposed to the default 9090.
So we had to edit the 'whitelist' in proxy.php file in the webclient folder.
$WHITELIST = array(
    "http" . (($_SERVER['SERVER_PORT'] == '443') ? 's' : '' ) . "://" . $_SERVER['HTTP_HOST'],
    "http://services.i2b2.org",
    "http://127.0.0.1:19090",  
    "http://127.0.0.1:8080",
    "http://127.0.0.1",
    "http://localhost:8080",
    "http://localhost:19090",
    "http://localhost"


I changed all entries where port 9090 was referenced to port 19090. 
Then I restarted Wildfly, even though I don't think that was necessary.
This resolved that error.
thanks!
