Now I have exactly the same problem as @cmuchuchuti.
When I try to connect ODK-X Survey with https://survey-demo.odk-x.org, “demo_user1”, “password”, the only answer I obtain is
Communication Error Occurred
Please verify your device browser can access your server.
The server is up and this is happening from tablets in different networks so I don’t think its really a network issue".
I must to explain that I have no problem when I do connect with the ODK-X Sync Endpoint Server at ITC, that is, https://odkx.climarisk.itccanarias.org, “aortegon”, “mypassword”. In this case, the connection ocurrs, and the synchronisation also ocurrs with no problem.
I also connect with no problem with the odk-x tables server, that is https://opendatakit-tablesdemo.appspot.com/, with anonymous and blank. I access the Tables demo app.
Following the instructions by @elmps2018 , I attach a copy of a log file, renamed to *.txt for security reasons. See finals lines, number 8584 and after.
