Hi All We've just updated our Central server from 0.8 to 0.9 to take advantage of some of the new Enketo integration. The upgrade itself has been successful, however when going to preview a form, Enketo throws up a Loading Error: "unable to verify the first certificate". We host ODK Central oursel…

Really appreciate your patience as got Enketo submissions ready, @MatthewMac and @dr_michaelmarks . We're especially eager to hear what you think of the public link feature that benefited a lot from my conversation with @chrissyhroberts . I think @dmenne is on to something and it's likely related to …

@MatthewMac do you have a firewall running by any chance? Please take a read through the upgrade notes for v0.9 and see whether that could possibly apply to you. That's the only thing I can really think of right now. It'd be helpful to hear from others whether they were able to successfully update …

Hi Hélène No firewall running. ufw is disabled. I went and built a whole fresh server (straight to 0.9 - no upgrade), again with our custom SSL. Same issue. Happy to test anything else. Matthew

@MatthewMac we're doing a big push to get v1.0 out with Enketo submissions. I don't have any more ideas at the moment. I think you're probably most interested in the submission functionality (is that right?) so I propose that we do more troubleshooting once v1.0 is in quality assurance and Team Cent…

@LN No problem at all. Very happy to wait (and not hold up development) for v1.0 If I find anything meanwhile, I'll certainly let you know.

Agree the submission functionality is key at LSHTM so hopefully we can get 1.0 soon and then resolve this.

In your setup, have you been able to work with ODK Collect? [image] Odk Collect with Custom Certificate: Android 5 (works), Android 7,8 (fails) Support I have installed ODK Collect on an Intranet with a Private Certification Authority created with easyrsa. The site inter…

@LN Unfrortunately still seeing the same issue with form preview after updating to 1.0 [image]

We have two Central servers setup currently. In answer to question from @dmenne On the one still running 0.8 ( @MatthewMac this is ODK-survey) App users work ok On the one we upgraded to 0.9 and now 1.0 App-Users seem to work but Enketo doesnt work. Will feedback on the preview / web-submission /…

@LN : I still have not been able to connect to Enketo with the private certificate that works with ODK Central. However, I have not put any research into it, because we have a much more serious problem with Enketo: uploading attachments to devices "behind the back", which works on ODK Collect with SS…

@LN Many thanks for the suggestion on the certificate. All is now working :slight_smile: Turns out the openssl util was stripping out the root and intermediate certs. I just needed to stitch them together manually. I can see that although the browser was happy with just the domain cert, enketo need…
