Invalid captcha code, please enable Javascript

Here's my current setup.
LHC installed in a subdomain, i.e live.mydomain.com, webserver: nginx/php-fpm
main website is on www.mydomain.comall sites (subdomain and mainsite) only use plain http mode, no https
chat configuration:
- set your domain: mydomain.com
- please enter explicit http mode: http:
- [ ] use secure cookie, unchecked
- [x] use session captcha, checked
but I still get the "Invalid capctha code, please enable Javascript" error message
The error shown up whether from main main site (widget) or from subdomain (live.mydomain.com)
Question: What is the right config to have the error disappear?Thank you

Re: Invalid captcha code, please enable Javascript

Hi,

Sorry but here all works. The only thing i see that php session is still under subdomain in my test environment but in any case it still works. I will fill enhancement that php session cookie also should be .mydomain.com but in general I do not think it will change anything in your case.
P.s even third party cookies dependency drop - all works as it should. Perhaps lhc cannot start it's session just in your server?

You can try add this line
session_set_cookie_params(0,'/','.domain.com');

in ezcomponents/Authentication/src/session/authentication_session.php before session_start();

In general once again not LHC problems...

Re: Invalid captcha code, please enable Javascript

I tried all combinations from every thread covering this problem but it doesn't go away. 
The weirdest thing is that it generates the "invalid captcha code, please enable javascript" error on some computers and not on others.  You suggest that someone probably changed a file but just like in my case, it appears on a vanilla installation.
Then you suggested that it has to be a problem on our end as it is working on your site, but that doesn't buy us anything, sadly enough.

Well,

Perhaps you have enabled session cookies? If you really want to solve this problem without personall look i really cannot tell what's wrong in your part... In any case there is commercial support if you need one...

Re: Invalid captcha code, please enable Javascript

Where can I disable session cookies?   
And what are they? I only know about cookies and session variables, the former being client based, the latter being server based, never heard of a combination of both.
I also ran GREP on your source code and there is no mentioning of "session cookies".

Re: Invalid captcha code, please enable Javascript

I tried both with and without and it doesn't make a difference.  How can it complain about captcha when it's disabled altogether?

Re: Invalid captcha code, please enable Javascript

That didn't help... but I discovered what the problem was.  The network that was failing to connect is using Load Balance Router and I discovered in the access logs that the client was trying to initiate a chat session using different IPs for different files. 
I assume the automated captcha knows what IP the client connected with and fails when the chat session is started using a different IP.
As this is an isolated problem that would only occur very rarely I don't see a need to pursue this from your end... but it's good to know what causes it in case it happens again.  Anyway, thanks a lot for you offer to help me!  I really appreciate it!

Re: Invalid captcha code, please enable Javascript

Ok I see, now it makes sense, because lhc uses IP to check that hash is valid, perhaps option to use ip or not would be helpfull, or just use user agent and avoid using ip for this at all. LHC itself for user side does not use php sessions at all to avoid this problem.

And thanks for letting me know about this. I'll try to adopt lhc to this edge case also in some time.
