Upgrade of Survey123 web install from 3.19 to 3.23, reverse proxy no longer works

[JeremyParker1]

Upgrade of Survey123 web installation from 3.19 to 3.23 on Linux platform went through without any issues.  We previously set up a reverse proxy using these steps and it worked without any difficulty for 3.19 with Apache:

However, we are having issues with the reverse proxy on 3.23, where the login screen never loads and there is just a spinning icon.  Accessing the application on the default port 5443 works.  Has anyone experienced this and may have a workaround?

Thanks in advance!

Hi @JeremyParker1 , this issue has gained our attention very recently. Could you try the following workaround and see if this works for you?

Add the following to your Apache configuration:

<Location "/survey123">
RequestHeader unset Accept-Encoding
AddOutputFilterByType INFLATE;SUBSTITUTE;DEFLATE; text/html text/plain text/xml Substitute 's#"/"#"/survey123/" #ni '
</Location>

Also, can you tell me the version of apache you are using and seeing this error?

Thanks,

Alison
