Can't get Dropbox app windows works withTransparent mode

CyrilRay

Hi,

i found different discussion about this problem but no solutions...

I tried to force the proxy setting in Dropbox with  UTM @IP:8080 still doesn't work.

I enabled the SOCKS4 and 5. same result.

I tried to do a standard profile for dropbox. same result

The only way i found is to made an exception to dropbox.com for authentification...or disable proxy [:P]

 

any idea where the problem is going from ?

 

Thanks

    I think this is a certificate pinning issue - the application knows the specific certificate to expect, and rejects all imitations.  The workaround is to create an exception to bypass https inspection.

    However this is a great opportunity to use log search to collect clues, and try exception settings to explore symptoms.  Does exempting from authentication make a difference? Is I.P.S. blocking any traffic?  Do web filter logs show anything blocked or warned?  Do any of the authentication service logs indicate an authentication failure?

    Note: A single 407 error in the web log indicates that UTM is asking for credentials.  This canbe normal. It does not imply an authentication failure.

    Maybe this will help you:

    (Copied)

    Allow Dropbox access to ports 80 (HTTP) and 443 (HTTPS).The Open button requires access to ports 17600 and 17603.The LAN Sync feature requires access to port 17500 (recommended)

    Salut Cyril and welcome to the UTM Community!

    First, I agree with Doug that this is a good opportunity to begin to familiarize yourself with the logs.

    My standard Exception is:
