Resolve host error

[ConstantinT]

Hello,

I have a problem regarding syncing with the latest version. It seems I can upload files and they appear in the web, but no files are shown in the app itself. My DNS works fine, as I said the upload works and as I understood the logs it find files. But it cannot display or download it. My network and also the DNS entry are IPv4 only. Do you need more information?

Here is a part of my log:

Do you think this is similar to #112 ?

I don't know. Partially it finds the folder obviously but fails to download files. I tried with my own DNS, but did not fix it. Do you need other information?
