Parse Dashboard shows blank white screen

Description:
When I log into the Parse Dashboard, it shows the red, green, blue loading bubbles for about 2 seconds and then a blank white screen.

When I tried SSH into the server, it says:

mongodb not running
apache not running
parse-dashboard not running
parse not running

So I tried “sudo /opt/bitnami/ctlscript.sh start” and it says:
“Starting services…”

However, when I tried “sudo /opt/bitnami/ctlscript.sh status”, it still shows that mongodb, apache, parse-dashboard, and parse is not running.

This is my first time using a Bitnami Parse Server on AWS. Any help or suggestions would be greatly appreciated.

Hi @thedashboardcompany

Thanks for using Bitnami Parse!

I have checked your logs and indeed all the services are running, regardless of the output of ctlscript.sh. Furthermore, accessing your URL results in success:

$ curl -kLI XX.XXX.XXX.224
HTTP/1.1 302 Found

Unfortunately, the bnsupport-tool failed to retrieve some files. Could you please run the following commands?

$ tail -n 35 /opt/bitnami/apache2/logs/error_log
$ cat /opt/bitnami/parse-dashboard/server.js | grep serverURL

Hi @thedashboardcompany

Thanks for sharing the commands’ output. I have launched a brand new instance (verion 4.9.3-2) and have not experienced any errors when accessing the dashboard. I see you are using an old version (4.3.0-2), is there any specific reason to?

Additionally, if you decide to remain using this version, could you please open the console panel in your browser to see if there are any errors there when accessing? If you are using chrome, this can be done as follows:

Hi @jcarmona

Thanks again for your quick response! Honestly, the real simple answer on why I’m using version 4.3.0-2 is because I don’t know how to upgrade my Parse Server (still very new to using the Parse server on Bitnami). I don’t know if you can see from your end, but thankfully, I have no data saved (or barely anything saved). So I have nothing to lose…just everything to gain from upgrading my Parse server.

Any guidance or assistance would be greatly appreciated. Thanks again for your help @jcarmona

jcarmona · January 13, 2021, 10:32am

If you don’t have any data to lose, the easiest way to upgrade is launch a brand new instance with the latest version.

Here you have a detailed guide that deals how to get started with Bitnami applications in AWS:
https://docs.bitnami.com/aws/get-started-marketplace/

Could that be an option for you?

Hi @jcarmona

Yes, that’s definitely an option for me (and probably best/easiest way like you said). I’ll launch a brand new instance of the Parse server (and delete this current instance since I’m not going to lose any data).

Thanks again for your help @jcarmona

My pleasure!

Please, update the thread with any new information

Hi @jcarmona,

So I installed a new instance of the Parse Server (latest version 4.9.3-4-r05) on AWS (didn’t touch or add anything). However, when I signed in for the first time, I got the same red, green, blue loading bubbles for about 2 seconds and then a blank white screen. I decided to SSH and run “sudo /opt/bitnami/ctlscript.sh status” and it says:

mongodb already running
apache already running
parse-dashboard already running
parse already running

Any suggestions on what I can do? Thanks!

jcarmona · January 19, 2021, 10:41am

Hi @thedashboardcompany

Thanks for reaching out again! I have launched the same version on AWS and did not run into problems (version 4.9.3-4-r05 - ami-007456a9c0ce86d38). Could you please try accessing using another browser?

If you run into the same problem, could you please check your browser’s console?

Hi @jcarmona

Thanks for the suggestion. I tried it on Firefox and Safari and it works! The only browser it didn’t work on (which happens to be the browser I use often) is Chrome. This is what was displayed on the browser console for Chrome:

Hi @thedashboardcompany

I think this is due to accessing the site over HTTPS. You can configure the asset to work with HTTPS, but could you please try accessing the page over regular HTTP?
