ODK AGGREGATE login error

I have error logging into ODK AGGREGATE page
https://opendatakit.appspot.com/multimode_login.htmlstrong text

when I enter the super-user ODK aggregate username which I provided during installation and the default password "aggregate", the webpage keeps on loading . And when I click "canceI" button I get the error
"Error: Username usertest1 not found" . The moment I click the "sign in aggregate password" the page keeps on loading.

Please suggest me some solution. Thanks in advance

https://opendatakit.appspot.com/ is the demo server. It doesn't have the default username and password. I'd encourage you to read through Getting Started docs.

I have installed ODKAggregate following the instructions in https://docs.opendatakit.org/aggregate-tomcat/ . After installation I followed the instructions given in readme.html. As a final it was mentioned that

visit http://localhost:8080/ODKAggregate/ Log in using the super-user's Aggregate username with password aggregate/ if you have not previously changed its password and go to the Site Admin / Permissions tab to change that password and to complete configuring the access rights for ODK Aggregate.

when call the http://localhost:8080 , the TOMCAT page gets loaded. But the url http://localhost:8080/ODKAggregate/ is given, I get 404 error. I am struck in this step. Please help me out.

Thank you. Then how can I perform operations like

  1. MANAGING FORMS IN AGGREGATE
    2.ADMINISTERING AGGREGATE
    3.WORKING WITH SUBMITTED DATA IN AGGREGATE
    if I am not able to login into the website. I want to know the username and password for this site

Hi @Vijayalakshmi,

It impossible to tell the issue with only that 404 error. Find the tomcat log file in your machine, it may more provide more insights on your issue.

As Yaw said earlier, that is a DEMO server, it has some demo form that are used for testing. CREDENTIALS cant be made public as the forms can be deleted.

There is another demo server where you can put your forms and test stuffs

Your log suggests you are running out of memory and I think your config shows that you've allocated a max of 256MB. That's way too small. I'd recommend a minimum of 1024 MB.
