Xerox App Gallery: Connection Error: An error occurred while trying to connect to the remote server.

I am encountering an error when attempting to open the Xerox App Gallery app on a VersaLink device. See attachment.

I captured a network trace of all traffic to and from the VersaLink B405 during problem replication. See attachment.

This was escalated to me as a SPAR from a field analyst who is having the issue on their demo room VersaLink C405. (CQGbl01225779)

Is this an app issue or a Xerox VersaLink issue?

Hello. 

 

Thank you for your message. 

 

This looks like it is a real connection issue. Can the Analyst connect to any of the Cloud apps (Scan and Print for OneDrive) from this device?

 

Could you ask the  Analyst to verify that the device Proxy is set in both of the required locations?

1) Connectivity -> HTTP....  go to the Proxy Server section to verify the setting. 

2) Apps -> EIP Settings....   the "Use Device Proxy Server" setting needs to be manually set to the same Proxy.

 

If this does not resolve the App Connection issue, please let me know.  I will investigate further. 

 

Just an additional note: 

They may also want to update their Certificate.  There is an updated certificate bundle located here: https://appstudio.external.xerox.com/app_studio/certs/XeroxSolutions-CertificateBundle.p7b

 

They can just download the bundle and go to System -> Security and install the certificates from there. 

 

Thank you,

I can recreate th eproblem on my lab device.

 

I have made sure these are set properly:

1) Connectivity -> HTTP....  go to the Proxy Server section to verify the setting. 

2) Apps -> EIP Settings....   the "Use Device Proxy Server" setting needs to be manually set to the same Proxy.

 

@PrintbyXerox app behaves the same way.

 

Where exactly would I upload the certs? On the Xerox MFD?

I captured a second network trace from a lab C405 that opens properly (attached).

 

The "bad" network trace shows the device attempting to go to IP address 134.213.169.45. And in the "bad" trace, it doesn't even get to the point where it checks the validity of a certificate.

 

In the "good" trace, the device attempting to go to IP address  13.121.1.242.

I tried installing the updated certs on the B450. Problem still occurs.

Be advised, the following is just something to try, as it fixes similar yet unrelated comm errors in other things (email in particular, but it is an easy thing to try, and maybe it will get you up and running, if it doesn't work, the people you are working with here can keep going with it)

 

On the one that doesn't work, do this
