Public bug reported: When self registration Captcha is on, the create button goes grey after pressing the create button and nothing is being processed and only stays on that screen.

I am not able to reproduce this on 2.23 or 2.24 (development branch). What browser are you using? Could you perhaps open the browser console and check if anything happens in the "console" or "network" tab? Any errors should be marked in read (at least in Firefox and Chrome). If you are unsure about how to open the console please refer to > javascript-console-in-different-browsers Thanks! \*\* Changed in: dhis2        Status: New =\> Incomplete > **···** > > -- > You received this bug notification because you are a member of DHIS 2 > developers, which is subscribed to DHIS. > [https://bugs.launchpad.net/bugs/1595071](https://bugs.launchpad.net/bugs/1595071) > > Title: >   Self Registration Captcha not working > > Status in DHIS: >   Incomplete > > Bug description: >   When self registration Captcha is on, the create button goes grey >   after pressing the create button and nothing is being processed and >   only stays on that screen. > >   When self registration Captcha is turned off the create button works >   fine. > > To manage notifications about this bug go to: > [https://bugs.launchpad.net/dhis2/+bug/1595071/+subscriptions](https://bugs.launchpad.net/dhis2/+bug/1595071/+subscriptions) ---

Thank you Halvdan Hoem Grelland (halvdanhg), We are using both Chrome and Mozilla and both are giving the same issues. These are the following errors that I receive once I click the create button: jquery.min.js:2 POST [http://197.189.252.38:8080/cserv/api/account](http://197.189.252.38:8080/cserv/api/account) 500 (Internal Server Error)send @ jquery.min.js:2ajax @ jquery.min.js:2accountSubmitHandler @ account.js:85handle @ jquery.validate.js:72(anonymous function) @ jquery.validate.js:92dispatch @ jquery.min.js:2h @ jquery.min.js:2 VM702:1 Uncaught SyntaxError: Unexpected token \< in JSON at position 0error @ account.js:93k @ jquery.min.js:2fireWith @ jquery.min.js:2y @ jquery.min.js:2d @ jquery.min.js:2 > **···** > > -- > You received this bug notification because you are a member of DHIS 2 > developers, which is subscribed to DHIS. > [https://bugs.launchpad.net/bugs/1595071](https://bugs.launchpad.net/bugs/1595071) > > Title: >   Self Registration Captcha not working > > Status in DHIS: >   Incomplete > > Bug description: >   When self registration Captcha is on, the create button goes grey >   after pressing the create button and nothing is being processed and >   only stays on that screen. > >   When self registration Captcha is turned off the create button works >   fine. > > To manage notifications about this bug go to: > [https://bugs.launchpad.net/dhis2/+bug/1595071/+subscriptions](https://bugs.launchpad.net/dhis2/+bug/1595071/+subscriptions) ---

I tried self-registering on that URL and got the same issue. It spits out a stack trace in the response which contains a Java security error. In short: your Tomcat is misconfigured and it cannot resolve the Java keystore to use for the HTTPS connection to Google's recaptcha servers. This causes the request to fail, which is why the registration screen is unresponsive. For you reference, here's the interesting part (the full error you will find in your server logs): java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty Though the error could be handled better for the user, this is a Tomcat issue and not a DHIS2 bug. Will close this one. \*\* Changed in: dhis2        Status: Incomplete =\> Invalid > **···** > > -- > You received this bug notification because you are a member of DHIS 2 > developers, which is subscribed to DHIS. > [https://bugs.launchpad.net/bugs/1595071](https://bugs.launchpad.net/bugs/1595071) > > Title: >   Self Registration Captcha not working > > Status in DHIS: >   Invalid > > Bug description: >   When self registration Captcha is on, the create button goes grey >   after pressing the create button and nothing is being processed and >   only stays on that screen. > >   When self registration Captcha is turned off the create button works >   fine. > > To manage notifications about this bug go to: > [https://bugs.launchpad.net/dhis2/+bug/1595071/+subscriptions](https://bugs.launchpad.net/dhis2/+bug/1595071/+subscriptions) ---

Dear Halvdan, We have deployed ssl and tested.We can access data visualizer and it works on ssl. We do not see any issues with our Tomcat setup and we are still having issues with this. We would like to know what is causing this problem. I can give you login details to our server, are you willing to have a look for us. > **···** > > -- > You received this bug notification because you are a member of DHIS 2 > developers, which is subscribed to DHIS. > [https://bugs.launchpad.net/bugs/1595071](https://bugs.launchpad.net/bugs/1595071) > > Title: >   Self Registration Captcha not working > > Status in DHIS: >   Invalid > > Bug description: >   When self registration Captcha is on, the create button goes grey >   after pressing the create button and nothing is being processed and >   only stays on that screen. > >   When self registration Captcha is turned off the create button works >   fine. > > To manage notifications about this bug go to: > [https://bugs.launchpad.net/dhis2/+bug/1595071/+subscriptions](https://bugs.launchpad.net/dhis2/+bug/1595071/+subscriptions) ---

Hi Evert, yes it does seem like you have an issue with the Tomcat setup - have a look at this thread: > invalidalgorithmparameterexception-the-trustanchors-parameter-mus Lars > **···** > > On Thu, Jun 23, 2016 at 1:37 PM, evert.bothma \ wrote: > > > Dear Halvdan, > > > > We have deployed ssl and tested.We can access data visualizer and it works > > on ssl. > > We do not see any issues with our Tomcat setup and we are still having > > issues with this. > > We would like to know what is causing this problem.

I am not referring to SSL for your domain. The recaptcha functionality is dependent on doing a server-to-server web request to Google's recaptcha servers. Your Tomcat instance fails to set up the HTTPS connection to said server because it cannot resolve any root certificates (which would be in the aforementioned keystore) from which to establish trust (aka. trust anchors). The link in Lars' reply should explain this in more detail. > **···** > > On Thu, Jun 23, 2016 at 1:37 PM, evert.bothma \ wrote: > > > Dear Halvdan, > > > > We have deployed ssl and tested.We can access data visualizer and it works > > on ssl. > > We do not see any issues with our Tomcat setup and we are still having > > issues with this. > > We would like to know what is causing this problem.

Dear Halvdan and Lars, Thank you very very much for your assistance. We managed to get a solution from the link that Lars gave us. We ran the command update-ca-certificates -f. This updates and refreshes the certificates in /etc/ssl/certs. It is working 100%. Again I want to say thank you. > **···** > > -- > You received this bug notification because you are a member of DHIS 2 > developers, which is subscribed to DHIS. > [https://bugs.launchpad.net/bugs/1595071](https://bugs.launchpad.net/bugs/1595071) > > Title: >   Self Registration Captcha not working > > Status in DHIS: >   Invalid > > Bug description: >   When self registration Captcha is on, the create button goes grey >   after pressing the create button and nothing is being processed and >   only stays on that screen. > >   When self registration Captcha is turned off the create button works >   fine. > > To manage notifications about this bug go to: > [https://bugs.launchpad.net/dhis2/+bug/1595071/+subscriptions](https://bugs.launchpad.net/dhis2/+bug/1595071/+subscriptions)
