Form update failed : collect can't connect securely to the server

1. What is the issue? Please be detailed.
By scanning the Qr code, the collect application adds a project. but when i try to get form in 'fill blank form' tab i'm getting a notification like Form update failed : collect can't connect securely to the sever

NOTE : I'm using a custom SSL certificate issued by CA therefore the connection is secure.

2. What steps can we take to reproduce this issue?

since it is self-hosted sever and it's for medical purpose I can't share the URL here.

3. What have you tried to fix the issue?

  1. I've tried to install old version of ODK-collect
  2. tried different smartphones with different OS versions
  3. app user access is provided for the specific project
  4. tried to connect maunally

4. Upload any forms or screenshots you can share publicly below.

Hi @Sundhar_Ganesh

You can follow the Central Advanced Configuration documentation.

Having followed the documentation, please feel free to post specific questions and issues.

Thanks @Ronald_Munjoma @yanokwa

I have merged both SSL and chain certificate using notepad++ and pasted at /data/central/files/local/customssl now it's working fine! :grinning:
