Enketo "Failed to load form"

We are facing problems opening the web link on Enketo for all the forms uploaded on the ODK central server.
Web page showing error: Enketo "Failed to load form"

One server is working well, but another server is not.
Please help to solve the problem.

Content Security Policy of your site blocks some resources

Any difference between the working server and the non-working server? Any changes made to the code or config on either?

Hi, Yaw,
Thanks for your response.
The working server is Linode, and non-working server is
PCL Government Cloud:

  • We are using a TCS cloud server with Ubuntu 20.04.6 LTS.
    • We have installed Docker manually.
    • Using custom SSL.

Please suggest a solution.

@Devendra_Patankar I'm in the same situation, have you ever found a solution?
