ABAP Webdynpro error on 3G Android tablet

[Former Member]

Hi,

I'm collecting ideas regarding the following problem.

I created an own Z webdynpro abap application in our ECC6 SP5 system, it has 3 landscapes, DEV, QUA, PRD.

The webdynpro application is working in DEV system

- on notebooks via WIFI

- on the Nexus 9 android tablet via WIFI and via 3G (with Spain Movistar as provider). We are using Sonicwall app for VPN.

It's working in QUA

- on notebooks via WIFI

- on the Nexus 9 android tablet via WIFI. We are using Sonicwall app for VPN.

It's not working in QUA

- on the Nexus 9 android tablet via 3G (with Spain Movistar as provider). We are using Sonicwall app for VPN.

We tried with different browsers.

Error message:

ERR_CONNECTION_REFUSED

It's a very common error message, so it might be hard to find the source of the problem.

All information is useful, thank you in advance for helping.

Best regards

Kedves Tamás,

The problem can be connected to the certificates or the internet zones.

This could be a local network issue, because the same device works via Wifi and does not with 3G.

The difference between them is that via Wifi the determined zone according to my assumption is intranet, and via 3G it is internet. This case the company firewall settings should be modified accordingly.

Regarding the certificates, it can happen that the device did not accept the server cert via 3G, but did via Wifi.

I would now check a dev_icm trace, which will maybe show something why the connection is refused from server side.

Best regards,

Gábor
