I saw a similar error to this one in a separate question, but I'd like to add more information to it. It may help others in debugging this error.
That is the error we get when we preview deployed forms in Enketo Express.
We've installed kobo-docker on an Ubuntu VM following the instructions on the page. The only file we've modified is envfile.server.txt as follows:
and we've set up the username, password and support email.
When we preview a form in Enketo Express, it takes a while to load and we finally get the error getaddrinfo EAI_AGAIN.
Is there a wrong configuration here, or is there some step we've omitted? I'm happy to provide more information.
Please only post your question in one of the three channels to avoid duplication.
