Dropbox Community ModeratorThat error is being reported by the iOS network client and that "-1005" error code in particular indicates that the network connection was lost.
Does this happen for all users all the time, or only some users/some of the time?
If it only happens sometimes, it may indicate that the network connection was lost for some reason; some of the following may be possible causes:
- if the network connection is lost, such as due to losing WiFi or cellular reception
- if the network connection switches between different interfaces, such as WiFi versus cellular
- if the app is quit during the connection
Those aren't conditions you can control of course, so you may want to add some automatic retrying to handle those.
If this isn't reproducible for all users/devices, it may be specific to the particular network connections of the affected users/devices. In that case, is there anything that may be interfering with HTTPS connections to api-content.dropbox.com on those network connections? For example, firewalls, proxies, VPNs, etc. may be interfering.
Dear GregDB,
thanks for the quick reply. As you assumed, it may be linked to the connection issues.
To handle these errors properly, is there a list/description of the different error codes available?
Best regards gcarl

It looks like Apple has a list of such errors documented here: https://developer.apple.com/documentation/cfnetwork/cfnetworkerrors
